First Responders Retirement System; establish.

SB 2907 establishes a new retirement system specifically for Mississippi first responders, including law enforcement officers, firefighters, emergency medical services providers, emergency management personnel, and public safety telecommunicators. The system, effective July 1, 2026, requires employee and employer contributions to fund retirement benefits, disability coverage, death benefits, and cost-of-living adjustments tied to the Consumer Price Index. It replaces existing retirement benefits under Article 3 of Mississippi's Public Employees' Retirement Law for these workers while allowing them to retain Social Security benefits. The bill creates an administrative board to oversee operations and aims to provide more generous benefits reflecting the hazardous nature of first responder work.
