HB 3171 amends provisions in the Texas Local Government Code concerning compensation and employment conditions for firefighters and police officers, focusing on collective bargaining and impasse resolution mechanisms. It emphasizes that municipal charters or collective bargaining agreements may establish the framework for resolving disputes, including compensation and employment conditions, which must align with prevailing private sector standards. The bill also clarifies the process for impasse resolution in collective bargaining, allowing for mechanisms prescribed in municipal charters or agreements to override certain arbitration provisions. The act applies to municipal charters, agreements, or arbitration awards effective on or after the act’s implementation.
