MI HB5780

Prohibits public employers from increasing wages or benefits above levels in effect when a collective bargaining agreement expires, during negotiations for a successor agreement.

Requires employees to bear any increased costs of health, dental, vision, prescription, or other insurance benefits occurring after agreement expiration, with employers authorized to make payroll deductions for these increased costs.

Prohibits retroactive wage or benefit increases greater than those in effect on the expiration date, with limited exceptions for compulsory arbitration under 1969 PA 312.

Applies to collective bargaining agreements that expired before June 8, 2011, limiting wages and benefits to levels in effect on that date.

Defines "expiration date" as the date set in the agreement without regard to party extensions during negotiations, and "increased costs" as premium or rate differences between prior and current coverage years calculated by coverage category.
