Modifies provisions relating to public employee retirement systems

HB 976 updates Missouri's public employee retirement system rules by defining automatic membership for regular workers, police, and firefighters based on their employer's coverage decisions. It specifies retirement payouts as a percentage of final average salary multiplied by years of service (e.g., 1% for regular employees, 1.25% for some firefighters), with temporary supplements for early retirees under 62 or 65. The bill directly affects all public employees in Missouri cities, counties, and local governments that participate in the retirement system. Key provisions include automatic enrollment for new hires and different benefit tiers based on job type and employer coverage choices.
