ment mandates a good faith effort by all parties. MCLA 423.215; MSA 17.455(15), Detroit Police Officers Association v Detroit, 391 Mich 44, 53; 214 NW2d 803, 808 (1974). A failure to bargain in good faith constitutes an unfair labor practice. MCLA 423.216; MSA 17.455(16). MERC has exclusive jurisdiction over all unfair labor practice questions. Detroit Board of Education v Detroit Federation of Teachers, 55 Mich App 499, 503; 223 NW2d 23, 25 (1974). If a strike constitutes an unfair labor practice, then MERC has jurisdiction over the matter.
In Detroit Board of Education, supra, we held that a strike need not constitute a failure to bargain in good faith:
"This broad definition of 'strike’ is said to include failure to bargain in good faith, since good faith bargaining is one of the 'duties of employment’. Therefore, concludes DFT, a strike is an unfair labor practice, furnishing MERC with exclusive jurisdiction.
"This reasoning is faulty on both logical and policy grounds. First, to say that a failure to bargain in good faith might constitute a strike for purposes of the definition of the latter term in MCLA 423.201; MSA 17.455(1) is not to say that every strike is an unfair labor practice. It is surely possible that a union could both bargain in good faith and still strike.” Detroit Board of Education, supra, at 504; 223 NW2d at 25-26. (Emphasis supplied.)
It is evident, therefore, that a strike need not indicate a failure to bargain in good faith. See also, NLRB v Insurance Agents’ International Union, supra. MERC therefore properly refused to accept the parties’ stipulation as binding.
In affirming the administrative law judge’s findings, the MERC appeal board stated that there was no evidence on the record to support a finding that the Teachers bargained in bad faith. This
