Labor: collective bargaining; calendar and schedule for school year; make prohibited subjects of bargaining. Amends sec. 15 of 1947 PA 336 (MCL 423.215). TIE BAR WITH: SB 0379'25

This Michigan bill amends labor law to prohibit public school districts from negotiating with teacher unions about 16 specific topics, including school calendars, staffing decisions, performance evaluations, and classroom observation policies. It directly affects school districts and their employee unions by restricting collective bargaining to only wages, hours, and basic working conditions. Key provisions add these topics to a formal list of "prohibited subjects" in bargaining agreements, meaning schools cannot discuss them during contract negotiations. The bill clarifies that operational decisions like school schedules (for state aid eligibility) and staffing reductions remain the sole responsibility of school districts.
