Labor: health and safety; employee communication regarding an occupational safety and health practice or hazard related to a communicable disease; prohibit an employer from taking an adverse employment action based on. Amends 1974 PA 154 (MCL 408.1001 - 408.1094) by adding sec. 66.

House Bill 4436 amends Michigan's occupational safety and health act to protect employees who communicate about workplace safety. The bill prohibits employers from firing or discriminating against an employee who discloses information about an occupational safety practice, workplace hazard, or communicable disease to the employer, other employees, a government agency, or the public. Employers are also barred from requiring employees to sign agreements or follow policies that limit such disclosures, rendering such provisions void. Additionally, the bill prevents employers from taking adverse action against an employee for wearing their own personal protective equipment that offers more protection than employer-provided gear. If an employer takes action within 90 days of a protected activity, it is presumed to be a violation.
