Labor: discrimination; certain protected attributes and characteristics of an employee; prohibit an employer from basing the employee's wage rate on. Amends 1978 PA 390 (MCL 408.471 - 408.490) by adding sec. 13b & repeals sec. 13 of 2018 PA 337 (MCL 408.943).

HB 4291 prohibits Michigan employers from paying employees different wages for equal work based on protected attributes like race, gender identity, religion, or age. It amends the state's wage law to require equal pay for jobs requiring equal skill, effort, and responsibility under similar conditions, while allowing exceptions for seniority, merit, or productivity-based systems. The bill explicitly defines "protected attributes" using the Elliott-Larsen Civil Rights Act and repeals a prior section (2018 PA 337, Sec. 13) that previously allowed certain pay differentials. It directly affects all Michigan employers and employees by mandating pay equity for comparable work. The law would take effect if passed, aligning Michigan's wage standards with broader civil rights protections.
