STATE OF MAINE MAINE LABOR RELATIONS BOARD Case No. 94-33 Issued: September 7, 1994 ____________________________ ) TEAMSTERS UNION LOCAL 340, ) ) Complainant, ) ) DECISION AND ORDER v. ) ) TOWN OF CAMDEN, ) ) Respondent. ) ____________________________) This case began with the January 27, 1994, filing of a prohibited practice complaint with the Maine Labor Relations Board (Board) in which Teamsters Union Local 340 (Teamsters) alleges that the Town of Camden (Town) has failed to bargain in good faith in violation of 26 M.R.S.A. 964(1)(E) (1988). More specifically, the complaint alleges that in November and December of 1993, during negotiations for a successor collective bargaining agreement, the Town, without notice, unilaterally changed a well-established past practice by permitting two non- unit applicants to become candidates in the filling of a vacancy in a sergeant's position. Additionally, the complaint alleges that the Town allowed these two applicants to submit applications prior to advertisement of the opening to bargaining unit members. The complaint avers that the Teamsters unavailingly objected to the alleged change in past practice. The Town denies any existing past practice. The Town's answer, by way of affirmative defense, requests the matter be deferred to arbitration pursuant to a grievance filed by the Teamsters on December 10, 1993. The Town asks for costs and attorney's fees. On March 24, 1994, Board Alternate Chair Kathy M. Hooke conducted a prehearing conference. Her April 11, 1994, Prehearing Conference Memorandum and Order, which denies the -1- Town's deferral motion, is hereby incorporated in and made a part hereof. On May 4, 1994, the Board, consisting of Alternate Chair Pamela D. Chute, Employer Representative Howard Reiche, Jr., and Employee Representative George W. Lambertson, conducted an evidentiary hearing at which the parties were afforded the opportunity to present evidence and argument. At adjournment of the hearing an agreed briefing schedule was established pursuant to which the last of the parties' briefs were filed June 6, 1994. The transcript was completed on June 9, 1994, and the Board deliberated the case on July 11, 1994. JURISDICTION The Town is a public employer within the meaning of 26 M.R.S.A. 962(2) (1988). The Teamsters have alleged that the Town has committed a prohibited practice proscribed by 26 M.R.S.A. 964(1)(E) (1988), during the six-month period immediately preceding the filing of the charge. See 26 M.R.S.A. 968(5)(B) (1988). The Board has jurisdiction to hear and adjudicate this matter by virtue of 26 M.R.S.A. 968(5) (1988). POSITIONS OF THE PARTIES The Teamsters allege that during the parties' negotiations for a successor to their contract which expired June 30, 1993, the Town changed a longstanding past practice1 of giving sole consideration in promotions to Camden Police Department (CPD) bargaining unit members, by considering non-bargaining unit _________________________ 1The complaint alleges a change in practice from bargaining unit promotional preference. Although in its opening statement at hearing the Teamsters refer to the preference as a depart- mental preference, and at points in the record the preference is referred to as for the full-time CPD work force, the Teamsters' post-hearing brief refers again to bargaining unit promotional preference. -2- applicants in the filling of a Sergeant's vacancy.2 The Teamsters contend that the Town considered as applicants and gave preferential treatment to3 two persons who were not employees of the Town and that the Town's actions constitute a change in the application of seniority and its effect on promotion. The Teamsters allege that every applicant who has been successful in the filling of every previous Sergeant vacancy has been a bargaining unit employee. The Teamsters contend that the Town was unsuccessful, prior to the complained-of change in practice, in obtaining a change in the language of the parties' contract's Management Rights clause, which would have permitted the Town to consider non-bargaining unit candidates.4 The Teamsters argue that this attempt establishes that the Town knew it did not possess the power to unilaterally promote and that the failure to obtain that language change constitutes a waiver of the right to change the parties' past practice. Finally, the Teamsters contend that the Town, on October 19, 1992, with notice only to non-bargaining unit employees and without the opportunity for the Teamsters to demand negotiations, changed its general personnel policy from one affording "maximum opportunity to currently qualified Town employees" and providing for external notice of vacancies "should there be no qualified _________________________ 2Although the Teamsters allege in the Complaint and argue in their post-hearing brief that Sergeants Sturdee, Cole, Arau, and Bickford were promoted from within the bargaining unit, these allegations were not substantiated. 3Although in the complaint the Teamsters state that these two candidates submitted applications for the Sergeant's position prior to the announcement of the vacancy to bargaining unit members, there is no evidence in the record to support this allegation. 4The Town unsuccessfully attempted to expand the wording of its Management Rights clause in successor negotiations by proposing language which would have confirmed or given the Town the authority "to direct the employees of the department, including the right to . . . promote." -3- personnel," to one which only "provide[s] reasonable opportunity to currently qualified Town employees," and permits the Town "to advertise as widely as is deemed necessary to attract a qualified field of candidates." The Town asserts that the Teamsters have not satisfied their burden of establishing a binding past practice. The Town alleges that there has been no consistent past practice in filling vacancies but, rather, a number of different approaches to filling vacancies for both Patrol and Sergeant positions. The Town contends that applicants Campbell and Bickford, whose candidacies the Teamsters contest, are both members of the Camden Police Department and that therefore the Town has satisfied any past practice of considering only "inside" candidates. The Town argues that the parties' negotiations respecting a successor agreement are irrelevant to the question of the existence of a past practice at the time of Campbell's application. Finally, the Town contends that the matter is one appropriate for deferral rather than consideration by the Board.5 FINDINGS OF FACT The Camden Police Department (CPD) is composed of nine full- time Patrol Officers, four Dispatchers, one Ticket Officer, five to six Reserves, a Chief, one Lieutenant and two Sergeants. The bargaining unit is comprised of Patrol Officers, Sergeants and Dispatchers. Pursuant to the terms of the parties' collective bargaining agreement then in effect, written notice was given of at least one party's desire to modify the agreement in a manner sufficient to cause the terms of the expiring agreement to remain in effect during the entire period of the parties' successor _________________________ 5The Town did not petition the Board for review of the Prehearing Officer's deferral decision as is required by Board Rule 4.07(D). The Town's renewed request is therefore hereby denied as untimely. -4- negotiations. Successor negotiations occurred in and from April, 1993, to and into February of 1994. The parties' present contract, effective September 1, 1993, and their most recent expired contract effective July 1, 1991, through June 30, 1993, both contain Management Rights clauses which provide that, "[t]he Town retains all rights and authority to manage and direct its employees except as otherwise specified in this agreement." The Management Rights clause proposed by the Town on May 21, 1993, during the most recent round of the parties' contract negotiations, would have added the following language to the existing clause: It is recognized by way of illustration and not by way of limitation that such rights and authority include, but are not limited to, the right and authority to exercise control and discretion over the organization and the efficiency of the operations of the department; to set standards for service to be offered to the public; to direct the employees of the department, including the right to assign work and overtime, to hire, examine, classify, evaluate, promote, train, transfer, assign and schedule employees in positions with the Town; to suspend, demote, discharge, or take other disciplinary action against employees; to increase, reduce or change, modify or alter the composition and size of the work force, including the right to relieve employees from duties because of lack of work or funds or other legitimate reasons; to determine the location, method, means and personnel by which operations are to be conducted; to establish, modify, combine or abolish job positions and classifications; to change or eliminate existing methods of operation, equipment or facilities; to establish, implement and maintain effective safety, health and property protection measures; to create, modify or delete rules and regulations; to take necessary action to carry out the mission of the department in cases of emergency. This change was suggested by Maine Municipal Association (MMA) employee Michael Wing, who the Town had retained for contract negotiations. The Chief and the Town Manager thought the Management Rights clause they had was fine but Wing thought -5- the longer version "would be more defendable." The matter was "not something the Town felt strongly about," so, when the Teamsters firmly resisted it, the matter was not pursued further by the Town. On February 8, 1994, the parties executed a memorandum outlining a successor agreement to replace the expired contract. Their agreement did not include the changes in the Management Rights clause which had been proposed by the Town.6 Seniority is defined in the parties' agreement as running from the last permanent date of hire. The parties' contract specifies that seniority "shall be a major factor in matters affecting layoff, recall and vacation preference." No mention is made in the Seniority article or elsewhere of the use of seniority in promotions. Nowhere in the contract is preference in either promotions or the filling of other vacancies given to bargaining unit, Union or CPD employees. Neither the present nor the past Sergeant job descriptions require Union or unit membership as a prerequisite to eligibility for the position of Sergeant. The parties' contracts do not contain a Zipper Clause or a Maintenance of Benefits Clause. The Town's personnel policies which address the issues of recruitment and promotion have been revised since Town Manager Moody came to the Town in May of 1991. During Moody's first year as Manager, he and the personnel committee reviewed the personnel policy. The new policy was brought before employees who are not part of the collective bargaining units, for comment, and was then approved by the Board of Selectmen in October of 1992. The Town's unilateral change of the personnel policy occurred during mid-term of the parties' July 1, 1991, through July 30, 1993, collective bargaining agreement. The Teamsters were given no _________________________ 6There is no evidence that abandonment of this proposal was in exchange for the Teamsters' agreement on any other contract language sought by the Town, or that it was abandoned in exchange for abandonment of any language sought by the Teamsters. -6- notice of the change, and the Town did not afford the Teamsters the opportunity to request negotiations over the change. Section 2.1 Eligibility of Article II, entitled RECRUITMENT AND EMPLOYMENT, TRANSFER, AND PROMOTION, of the Town's personnel policy, in effect from 1985 until October 19, 1992, states: It is the policy of the Town of Camden that all positions within the Town be filled by fully qualified[7] people who have been evaluated based on job related criteria. Eligibility for appointment, promotion, or transfer shall therefore be based on such qualifications. It is also the policy of the Town to provide maximum opportunity to currently qualified Town employees. (Emphasis added). Section 2.2 of this Article entitled Announcement of Vacancies states, in pertinent part: Notice may be given externally should there be no qualified internal applicants, or if necessary to develop a broader base of applicants. The Town's October 19, 1992, revised "Eligibility" policy states, instead of "maximum opportunity", that, ". . . It is also the policy of the Town to provide reasonable opportunity to currently qualified Town employees." (Emphasis added). Similarly, the revised policy reflects a change in the Announcement of Vacancies provision. The October 1992 version states, in pertinent part: It shall be the policy of the Town of Camden to advertise as widely as is deemed necessary to attract a qualified field of applicants. However, all job notices will be posted on bulletin boards in Town work sites. The promotion at issue is the first which has occurred since the _________________________ 7There is no direct evidence establishing whether, in light of the Sergeant job description's police experience requirement and requirement of Maine Criminal Justice Academy "Basic School," waiver, or eligibility, there were any Town employees "qualified" to apply for the Sergeant position. -7- personnel policy was revised. The Town Manager considers the Town's personnel policy to apply only to unrepresented Town employees, and not to constitute a supplement to the employment relations of represented employees respecting matters not addressed contractually. In practice, if a Town employee meets hiring criteria they're given preference. Nothing in the Town's personnel policy imposes any time limits on postings of vacancies. Camden sponsors one Patrol Officer as an agent of the Maine Drug Enforcement Agency (MDEA). Assignment to the MDEA is on an annual basis. For five years Cameron Campbell has been an undercover agent of the MDEA sponsored by the Town of Camden. MDEA's predecessor, BIDE, brought Campbell's name to the CPD. Campbell is classified by the MDEA as an Investigator Supervisor and is considered a Reserve Officer by Camden. His Camden reserve status and his MDEA Agent service commenced simultaneously. He is supervised by, and his daily activities are directed by, the MDEA. Camden pays Campbell's salary and the MDEA reimburses Camden. The MDEA sets Campbell's pay at $13.50/hour ($560/week), the equivalent of a State Police Sergeant based on a 42-hour week. The MDEA Agent rate is $3.00 more than that paid a Camden Patrolman and $2.40/hour more than a Sergeant. MDEA is presently three to four months behind on its reimbursements. The Teamsters played no role in establishing the terms of Campbell's employment contract. The MDEA position was not posted for CPD regular full-timers to participate in. MDEA Agents receive the same non-wage benefits as fellow employees receive in the departments from which they originate. A contract for services exists between Camden and the MDEA respecting the full nature of the employment and use of Campbell as an agent of the MDEA. A contract between Campbell and the Town establishes Campbell's employment relationship with the Town and the MDEA. Campbell's unique employment arrangement has been -8- reviewed and approved annually by the Town's Board of Selectmen. The Teamsters have not proposed that the Town bargain over the matter of Campbell's employment conditions. Senior Patrolman Rob Laite's predecessor as chief Teamsters' shop steward "did raise a concern and wanted it to be made known that if we accept this person or if he's accepted that he have no bumping rights." The current agreement between MDEA and Camden was signed on December 6, one day prior to the posting of the Sergeant's vacancy. The contract between Camden and the MDEA specifies that the "MDEA director is not bound by any final or intermediate decision of any grievance procedure." Campbell's contract with the Town, by which he is specifically appointed a "Special Police Officer within the meaning of Title 30-A MRSA Section 2672" waives all rights to which Campbell may be entitled under the collective bargaining agreement, including "longevity, seniority, accrued benefits, and any other rights that are available to regular police officers". Campbell's contract with the Town specifically states that "he is not hired for the purpose of becoming a regular member of the Camden Police Department" and that "[t]he Town would not be hiring [him] for any other purpose were it not for the Town's participation in the MDEA program." The Town has reached an agreement with no one affecting its ability to employ Campbell which is in any way enforceable by the Teamsters. Burgess was Chief when Campbell was first assigned to the MDEA. Campbell has never been evaluated as a regular member of the CPD. Regular employees receive an annual performance evaluation. Campbell does not report for work to the Camden Police Department although he does come by to pick up his check on Fridays. Campbell does not attend departmental meetings, or wear a CPD uniform, has not appeared on a call-up list prior to the present promotional exam and has never attended weapons qualification at the firing range. Campbell has not attended -9- mandatory departmental meetings at the Maine Chief's Association. Prior to the MDEA Campbell worked as a Patrolman and as a Detective for the Rockland Police Department. Campbell has worked with the CPD on numerous drug cases. CPD Patrol Officers ordinarily perform a 6-month probation. Bickford was well known in Camden and was a Deputy with the Knox County Sheriff's Department. He is a Detective there now. Bickford began working for the CPD in June of 1993 as a Reserve Officer primarily working OUI roadblocks. Reserves perform five hours of formal training monthly. Working a shift has satisfied the training requirement in the past. Reserve officer vacancies are not posted and no newspaper articles have announced their engagement by the Town. Reserves are generally recruited by word of mouth. Bickford has not attended Departmental meetings or mandatory departmental training sessions. Reserves work part- time and are not bargaining unit members. There is no alleged correlation between service as a Town reserve officer and eventual hire as a patrolman. Senior Patrol Officer Rob Laite has been the CPD shop steward for the past five years and was an assistant steward for the three previous years. In his present capacity he is involved in all forms of discipline affecting unit employees respecting which grievances are filed. Laite's duties as steward include bargaining team membership. He was on the Teamsters' team in the most recent negotiations. Laite was a part-time reserve dispatcher in 1985, a full-time dispatcher in 1986, and patrolman in 1987. Laite's position at the CPD is not an annual appointment. There have been two Sergeant promotions in the department during Laite's tenure. The two vacancies occurred at some unsubstantiated date more than eight years ago, as the result of a resignation and an extended medical leave. A written test, an -10- interview and an oral board were employed in filling the vacancies. Unit employees Wakelin, Hall and Roberts agreed among themselves to limit their competition for Lieutenant and Sergeant vacancies, by agreeing that Wakelin and Hall would not apply for Lieutenant vacancies and that Roberts would not apply for any Sergeant vacancy. Three applicants took the promotional examination: Patrolmen Hall, Wakefield and Main. Hall and Wakefield, who were promoted into the vacancies, were the most senior applicants and had been serving in acting Sergeant capacities. There is no indication whether there were any applicants either from outside the department or outside the bargaining unit, in the promotion process. There is no evidence that there has ever been an applicant or candidate for any Sergeant vacancy from outside the bargaining unit. There is also no evidence of any internal or external advertisement of any Sergeant vacancy prior to the one at issue in this case. There have been no Sergeant selections since Chief Burgess came to the Department as Chief in February of 1989. There has been only one Lieutenant promotion (promotion out of the unit) in the present Chief's tenure and there was only one candidate for that promotion. The present Sergeant vacancy occurred after Sergeant Hall went out in January, 1993, on a work related injury, filed a workers' compensation claim, reached a settlement with the insurer and then resigned on November 22, 1993. Chief Burgess came to the conclusion sometime in or after late summer of 1993 that Hall "was not very likely to come back." When it appeared that Hall would not return, Burgess went through the Department's personnel files looking for criteria that had been used in previous promotional vacancies. He was unable to find consistent criteria. Burgess discovered that an International Personnel Manager's Association (IPMA) test and a test administered by the MMA had previously been used. Advertising of the position was delayed for two weeks after Hall's resignation while approval of -11- the Town selectmen was obtained.8 Burgess did not advertise the Sergeant's position outside the department. Chief Burgess set about developing a process and criteria to be used in the Sergeant selection. He developed weighting to be applied to the promotional criteria based on his experience and on research of law enforcement literature addressing the subject. Burgess's experience weighting grants twice the points annually for service with Camden as compared to other departments in an attempt to grant an edge to candidates who had all of their experience with the CPD. Service with the MDEA under Burgess' weighting would be discounted as would credit with any other agency outside the CPD. There was some undisclosed dispute over the credit to be given for inside and outside department credit for reserves. No grievance was filed regarding that issue. The first notification which Laite received of the Town's intent to fill the vacancy in the Sergeant's position was a December 2, 1993, article appearing in a local newspaper, the Courier Gazette. Shortly after the newspaper article ran, a notice was put up on the board in the back of the station at the CPD announcing the availability of the position and soliciting those interested to send letters of "intent" to the Chief. The notice advertising the Town's intent to fill the Sergeant's position, posted on December 7, 1993, states: As you probably already are aware, Sgt. Hall has resigned from Camden Police Department. Peter's resignation has created an opening as Police Supervisor within the department. The basic criteria to be eligible to test for this position are as follows: 1. A minimum of four years of full time law enforcement experience; 2. Completion of the Maine Criminal Justice Academy Basic Police School or equivalent certifica- tion; 3. Possess a valid Maine driver's license. If _________________________ 8The record does not establish whether this approval was of the settlement agreement, of the resignation of Hall, or of the Department's intent to fill the Sergeant's position. -12- you meet these criteria and are interested in testing for the position forward a letter of intent to me no later than 12/15/93 at 1600 hrs. I will provide you with the Police Sgt.'s updated job description; a recommended study list for the written exam; written and oral board test dates; and a breakdown of promotional criteria. If you have any questions concerning your eligibility or the letter of intent, see me. Good luck. This announcement of the Sergeant vacancy does not significantly differ in content from the CPD's September 6, 1990, Patrol Officer vacancy announcement or its August 20, 1990, Lieutenant vacancy announcement. The notice announcing the vacancy required initialling in acknowledgement of receipt of notice of its contents. A number of employees who were interested signed the notice in acknowledgment. Bickford and Campbell, who the Teamsters had been (unspecifiedly) advised were going to be considered, never initialled the notice. Failing to sign the notice was not a bar to candidacy. Laite inexplicably believed signing the notice would preserve an individual's candidacy despite failure to submit a letter of "intent." Laite tendered a letter of "intent" the day after the posting of the notice. Bickford came to the Department to ask for an application for the Sergeants' exam. The Chief received letters of intent from Laite, Miller, Gagne, King, Campbell and Bickford. Burgess considered Bickford and Campbell to be employees of the Department. In response to letters of intent applicants were sent letters telling them the time, date and place of the examination and giving them a study list published by the IPMA. The letter also said that the Chief would supply updated versions of the job description. Burgess had recently added numerous Special [Eligibility] Requirements for Sergeant candidacy but these had not been added on to the existing job description. Lack of updated descriptions prevented their promised distribution to applicants. The testing and -13- promotional criteria for the Sergeant's vacancy were announced by Chief Burgess in a memo, which states: The testing for the position of Sgt. with the Camden Police Dept. will consist of a written test (30%); an oral board exam (30%); analysis of prior evaluations and training (20%); seniority points (10% @ 4 points for minimum and 2 points per year up to 10 years with CPD and 1 point per year with other law enforcement agencies); and an interview with Lt. Roberts and I (10%). Any questions concerning this procedure should be directed to me. Burgess spoke with Laite about the promotion process. Laite asked if Bickford and Campbell were going to be permitted to test for the vacancy. When Burgess said they had expressed an interest and that as far as he knew they were, Laite informed Burgess that the membership didn't think it was fair that he was "going outside to hire." Laite subsequently filed a grievance, on December 10, 1993, objecting to consideration of Campbell and Bickford for the promotional exam. The grievance report states, in pertinent part: "We feel that this is a unilateral change in working conditions by allowing these two gentlemen to take part in the promotional process[sic] therefore a violation [of the] contract." On December 14, Teamsters Business Agent Ernie Canelli sent a letter which, inter alia, notified the Town Manager of the existing grievance and of the Teamsters' intent to file a prohibited practice with the Board if the matter was not settled at the Town Manager's level. Laite spoke to the Town Manager and made the Teamsters' position known to him. On December 15, Burgess issued a memo listing the candidates to be tested. The list was intended to permit the tested employees to pass through security at the test site. On December 16, Burgess announced the date, time and location of the test. Also on December 16, Burgess wrote Laite, as follows, regarding the 12/10/93 grievance: -14- Following our meeting of 12/14/93 regarding this issue, here is my written response in compliance with our current grievance procedure: I cannot grant your grievance because there is no language in the current contract relative to promotional testing criteria and I therefore believe it is Managements right to establish those criteria. There have been no promotions of union covered positions since my being hired as Chief of Police so I do not believe I am violating any past practice or long standing work conditions. The grievance was never taken to arbitration. The test was administered on December 21, 1993; Bickford and King did not take the test. No one complained about their scores which were revealed the same day as the examination. Campbell scored highest, followed by Miller, Laite and then Gagne. The Sergeant's position is still vacant. To date, only the written exam has occurred. Neither oral boards, reviews of evaluations and training, nor interviews have transpired. Burgess has not formally assigned experience points to any candidate although he has approximated those of Campbell, Allen and Miller. Burgess has not conducted interviews because he does not want to bring someone on then possibly have to lay them off. DISCUSSION The Teamsters allege that the Town has unilaterally abandoned a well-established non-contractual past practice in the filling of vacant Sergeant positions, of accepting candidates only from within the bargaining unit. We have previously outlined the rationale and ambit of our unilateral change rule, which applies to allegations such as those involved in the instant case, as follows: Changes in the mandatory subjects of bargaining implemented unilaterally by the public employer contravene the duty to bargain created by 965(1) of -15- the Act and violate 26 M.R.S.A. 964(1)(E). The rationale behind this principle of labor law is that an employer's unilateral change in a mandatory subject of bargaining "is a circumvention of the duty to negotiate which frustrates the objectives of [the Act] much as does a flat refusal" [to negotiate]. NLRB v. Katz, 369 U.S. 736, 743, 82 S.Ct. 11007, 1111, 8 L.Ed.2d 230 (1962); Lane v. Board of Directors of M.S.A.D. No. 8, 447 A.2d 806, 809-810 (Me. 1982). In order to constitute a violation of 964(1)(E), three elements must be present. The public employer's action must: (1) be unilateral, (2) be a change from a well-established practice, and (3) involve one or more of the mandatory subjects of bargaining. Bangor Fire Fighters Association v. City of Bangor, MLRB No. 84-15, at 8 (Apr. 4, 1984). An employer's action is unilateral if it is taken without prior notice to the bargaining agent of the employees involved in order to afford said representatives reasonable opportunity to demand negotiations on the contemplated change. City of Bangor v. A.F.S.C.M.E., Council 74, 449 A.2d 1129, 1135 (Me. 1982). Auburn Firefighters Association Local 797, IAFF, AFL-CIO v. Paula Valente, No. 87-19, slip op. at 7, 10 NPER ME-18017 (Me.L.R.B. Sept. 11, 1987) (quoting Coulombe v. City of South Portland, No. 86-11, slip op. at 11-12 (Me.L.R.B. Dec. 29, 1986), 9 NPER ME- 18008, citing Teamsters Local Union No. 48 v. Eastport School Department, No. 85-18, slip op. at 4 (Me.L.R.B. Oct. 10, 1985), 8 NPER ME-17003). Because the Town does not dispute that its actions were unilateral or that they involve a mandatory subject, the dispositive issue in this case is whether there has been a well- established practice in the filling of Sergeant vacancies, of limiting applications exclusively to existing members of the bargaining unit. The entitlement of employees to the continuation of the status quo respecting mandatory subjects is unaffected by whether the status quo "result[s] from negotiations or from past practice." See Teamsters Local Union No. 48 v. Bucksport School Department, No. 81-18, slip op. at 4 (Me.L.R.B. Dec. 22, 1980). The burden of proving that a bargaining-unit- -16- only zone for Sergeant promotions was a well-established practice of the parties is on the Teamsters. See Teamsters Local Union No. 48 v. Town of Fort Fairfield, No. 86-01, slip op. at 9 (Me.L.R.B. Jan. 24, 1986). As is more fully explained below, we find that the Teamsters have not satisfied their burden of proof. The Town's Management Rights Proposal We are not convinced that the Town's proposal and subsequent withdrawal of a wide-ranging Management Rights clause in successor negotiations constitutes an acknowledgment by the Town of an existing practice of a bargaining-unit-only promotion zone for Sergeant vacancies. We do not agree with the Teamsters that the Town's proffer of the proposal indicates that the Town doubted its unilateral right to promote. First, reference to an amorphous "right to promote" is only one of a great many facets of the Town's proposed language. Second, the clause was apparently half-heartedly proposed and unremarkably abandoned. Third, the evidence does not reveal that a bargaining-unit-only promotion zone for Sergeant vacancies was ever discussed or even mentioned in negotiations. Finally, although the proposal was proffered in April or May, subsequent to the January start of Hall's lengthy work injury absence, the evidence establishes that the Town first suspected Hall would not return only in, or after, late summer 1993. Hall actually resigned much later, near the end of November, making the need for a replacement a certainty. If, in fact, the Town was possessed of uncertainty about its ability to unilaterally promote and desired to firm-up its prerogative, the language would doubtless have been more specific and the negotiations over its inclusion more protracted. The Personnel Policy Change The Teamsters have not charged that the Town committed an unlawful unilateral change when it modified its general personnel policy in October or November of 1992. The Teamsters do not charge that the Town's general personnel policy is the basis of -17- the past practice at issue here9 or that any improper application of the policy by the Town constitutes an unlawful refusal to bargain. The Teamsters' complaint charges a violation of an alleged bargaining-unit-only zone for Sergeant vacancies. The personnel policy, on its face, applies only to candidate recruitment and selection preference favoring Town employees. Additionally, the Teamsters have not shown the policy to be violative as applied.10 The evidence respecting the change in the Town policy no more strongly supports the Teamsters' suggestion that the Town was attempting to undo the established practice of a unit-only promotion zone for Sergeants than it supports an hypothesis that the Town was attempting to reduce the historical preference for "insiders" applicable to its unorganized Town employees, to bring it into line with the lack of preference for "inside" employees which existed at the CPD. In any event, the October '92 change in the personnel policy was so temporally removed from the December '93 promotion process that its probative value is dubious. Moreover, it is unlikely, in light of the comparative infrequency of turnover at the CPD, that the personnel policy change was part of a systematic effort to attenuate or eliminate the influence of seniority in Town personnel matters. Accordingly, we are not required to determine whether Campbell and Bickford are "employees" of the Town. If such a determination were relevant to the charged prohibited practice, we would be inclined to find, only in regard to the use of the ____________________ 9We will not comment, on this record, concerning the soundness of the Town's conclusion respecting whether its general personnel policy is applicable to bargaining unit members in circumstances where neither the contract nor a contrary past practice are controlling. 10There is no evidence, respecting the present or previous Sergeant vacancies, that bargaining unit members are, or have previously been, the only "currently qualified" Town employees. -18- word in the personnel policy, that Bickford as a "reserve officer" and Campbell as a "special officer" are Town employees in the broadest sense of that word. Such a finding would not require a determination of whether they are public employees within the meaning of the Municipal Public Employees Labor Relations Law. Past Sergeant Vacancies The Teamsters allege that applications for Sergeant vacancies have always previously been limited to bargaining unit members. To establish the existence of this practice the Teamsters have proven that the last two Sergeants selected were Patrol Officers at the time of their applications and that one additional unit member also applied. Additionally, the Teamsters have proven that all previous successful candidates have been bargaining unit members. The Teamsters' proof is inconclusive, however, respecting whether any persons not then current members of the bargaining unit have ever been sought or permitted to apply for consideration in the filling of Sergeant vacancies. Although the Town is in the best position to tender reliable evidence concerning the probative issues of whether in previous Sergeant promotion procedures the vacancies were advertised outside the department, and whether non-unit candidates were ever considered, we refuse to infer that such evidence if presented would run against the Town, for the following reasons. Figuring foremost in our refusal to draw the inference is the fact that there is no evidence in this record that Town officials were requested to provide such information by the Teamsters. Furthermore, subpoenas were not requested by the Teamsters to secure the attendance and testimony of any current or former Town official to render probative testimonial or documentary evidence respecting these, or similar, facts. Finally, the Teamsters neglected to adequately question, on direct or cross-examination, Town officials respecting these matters. -19- We also reject the Teamsters contention that the testimony of Chief Burgess, respecting the apparent arrangements among some unit members with regard to limiting their mutual competition in the filling of the Lieutenant and Sergeant vacancies eight years ago, tends to establish the alleged past practice. CONCLUSION The existence of an enforceable past practice may be proven by evidence of the conduct of the parties in dealing with a mandatory subject, which reveals a practice that is long- standing, frequently observed and consistently applied. An enforceable practice may also be proven by evidence of less frequent dealings of the parties respecting a mandatory subject, where the evidence reveals a clear and unmistakable shared expectation of resolving similar cases in the same manner. The proof of the Teamsters in this case satisfies neither of these methods. The Teamsters have established that all successful candidates for previous Sergeant promotions have been unit members, and that three bargaining unit members were candidates in the most recent filling of Sergeant vacancies which occurred eight years previous. We are unwilling to make the leap from these facts to a conclusion that there exists a well-established practice of a bargaining-unit-only promotion zone for the filling of Sergeant vacancies. Because the Teamsters have not satisfied their burden of proof, we conclude that the Teamsters' complaint must be dismissed. Accordingly, we issue the following order. -20- ORDER On the basis of the foregoing findings of fact and discussion and by virtue of and pursuant to the powers granted to the Maine Labor Relations Board by the provisions of 26 M.R.S.A. 968(5) (1988 & Supp. 1993), it is hereby ORDERED that the Teamsters' January 27, 1994, Complaint be, and hereby is, DISMISSED.
