In this аppeal a teacher seeks a determination of seniority rights vis-a-vis another teacher. We conclude the petitioner is not collaterally estopped by a prior determination of the other teacher’s seniority rights. We reverse and remand for further proceedings.
In the spring of 1983, Independent School District No. 347, Willmar, discontinued the position of technical tutor in its area technical-vocational school. Dale Ru-ter, the incumbent tutor, was placed on unrequested leave over his objection that he was also qualified to teach carрentry and was entitled to bump Edward Pirrotta, a less senior teacher in the carpentry department. On appeal to the court of appeals, that court reversed the school bоard’s decision and stated, “Ruter must be allowed to take the position of a less senior carpentry teacher.”
Ruter v. Independent School District No. 347,
It was now Edward Pirrotta’s turn to protest. He requested a hearing to contest his placement on unrequested leave. Pir-rotta сonceded the court of appeals’ decision in the
Ruter
case had determined Ru-ter’s schoolwide seniority should take precedence over Pirrotta’s departmentwide seniority, but Pirrоtta claimed there was another issue not raised in the
Ruter
proceeding, namely, whether Ruter’s carpentry license had been obtained in time to give him any seniority in carpentry. The school bоard, however, following the recommendation of the hearing officer, concluded it was required to follow the court of appeals’ decision and installed Ruter in the carpentry pоsition. Pirrotta, therefore, was placed on leave. The court of appeals affirmed the school board’s action, ruling that Pirrotta was collaterally estopped by the
Ruter
decision from relitigating any seniority issues.
Pirrotta v. Independent School District No. 347, Willmar,
I.
Pirrotta claims he should not be collaterally estopped from litigating his seniority *22 claim because he was not a party nor in privity with a party to thе Ruter case. We agree.
Everyone agrees Pirrotta was not a party. Also, it is conceded Pirrotta did not have any “controlling participation” in the
Ruter
case, so privity cannot be found on that basis.
See, e.g., County of Ramsey v. Stevens,
II.
If collateral estoppel is not a bar to Pir-rotta’s claim, both Pirrotta and the school district' then ask us to reach thе seniority issue on its merits. Pirrotta concedes the court of appeals was correct in Ruter in holding that seniority in the vocational-technical school was not departmentwide, but schoоlwide. He asserts, however, that even under schoolwide seniority, he is senior to Ruter for teaching carpentry. He bases this claim on the negotiated unrequested leave provision in the mastеr contract, which reads:
WAVTI [Willmar Area Vocational-Technical Institute] seniority rights shall be limited by the current licensure at the beginning of each fiscal year, which is July 1. (That is, for a WAVTI instructor to take a position he/she must have a current license to teach that position.)
(Emphasis added.)
In other words, bumping rights are to be determined according to licensures held as of July 1. But of which year? Ruter bumped Pirrotta from the carpentry position for the 1983-84 school year. Ruter obtained his carpentry license during the preceding 1982-83 school year, in September 1982. Consequently, at the beginning of the school year preceding the school year in which bumping was to take place, i.e., on July 1, 1982, Ruter did not yet have a carpentry license. However, at the beginning of the school year in which bumping was to occur, i.e., on July 1, 1983, Ruter did have a carpentry licensure. Whiсh July 1 is the seniority “freeze” date? The school district says it should be July 1, 1983, while Pirrotta says it should be July 1, 1982.
We decline to answer the question. It appears we do not have all the facts, such *23 as the collective bargaining history of the master contract, to determine the intent of the contracting parties on the proper seniority freeze date. Nor are we factfind-ers. Moreover — and Edward Pirrotta will appreciate this — we should not be determining Ruter’s seniority status without Ru-ter here.
We do hold, however, contrary to the school district’s contention, that Pirrot-ta did not waive his claim of seniority over Ruter by failing to grieve the posted seniority list. Unlike
Blank v. Independent School District No. 16,
We remand this matter, therefore, to the school board for further proceedings. The school district should reconvene Pirrotta’s unrequested leave hearing, giving Ruter notice of a right to intervene, and decide whether the Pirrotta-Ruter seniority rights are to be determined as of licensures held July 1, 1982, or July 1, 1983. 2
III.
It is indeed unfortunate this matter, twice in the appellate courts, must now go back yet again for further proceedings. Especially is this so for the school district which has found itself caught in the protracted legal crossfire of two teachers. Part of the problem has been a poorly drafted unrequested leave provision in the master contract and a seniority list which failed to réflect the parties’ contractual understanding. In Blank v. Independent School District No. 16, supra, we stressed the importance of seniority lists. If properly drafted and not grieved, they become final and obviate prоblems that can arise later when staffing decisions must be made. But we recognize, too, that part of the problem confronting the parties in this case was a lack of direction in the statutes on how to proceed when there are conflicting seniority claims and no apparent forum for more than one teacher at a time to be heard.
Until the legislature may act, we hold that at the second stage of a hearing to place teacher A oh unrequested leave, i.e., at the stage' where teacher A is claiming a right to bump teacher B, the school district shоuld give notice to teacher B that he or she may intervene to protect their seniority rights, and that failure to intervene will bé deemed acquiescence in the school district’s action. In somе schools, especially those with large faculties, bumping teacher B may cause further bumping, which may require further invitations to intervene, but, even so, it would seem the best way to avoid serial hearings is to provide one hearing, if possible, at which all concerned can be heard. Ordinarily, the relative seniority rights of the faculty are not in dispute, so in most cases teacher B may choоse not to intervene; but when disputes do arise, as here, a hearing at *24 which both affected teachers may appear should be provided.
Reversed and remanded.
Notes
. In
Aerojet,
the Fifth Circuit said a nonparty may be bound by a prior judgment "if one of the parties to the suit is so closely aligned with his interests as to be his virtual representative.”
Id.,
. The parties, if they all agree, could, as an alternative, submit thе issue of the proper seniority freeze date to grievance arbitration before an experienced arbitrator under the terms of the master contract. The issue involved is one оf general contract administration, which is ideally suited for grievance arbitration, and need not involve the courts. The parties to arbitration would include the parties to the master contract, namely, the exclusive representative and the school district. The neutral arbitrator’s decision would be final and binding on all concerned. The only issue remaining between Pirrotta and Ruter is the mеaning of the master' contract language and, once this is resolved, the relative seniority of the two teachers will be evident. We recognize, however, that the seniority freeze date issuе has arisen in the unrequested leave hearing and may be resolved there. Only the "second stage” of the unrequested leave hearing need be reconvened.
