608.07000 – Waiver by Union; Contract Waivers; Bargaining History Estoppel; Disclaimer; Supersession

When the contract is clear and unambiguous on its face, Board does not need to go beyond plain language of the contract to ascertain meaning; p. 11, 12 and 18. Where contract language ambiguous, extrinsic evidence (bargaining history, parties' conduct, etc.) is properly considered by Board to determine the meaning of the contract; p. 11, 12 and 18.
