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

House Bill 4439 amends the Michigan occupational safety and health act to protect employees who refuse to work due to a reasonable belief of exposure to a communicable disease or unsafe condition. This protection applies if the employee first requested the employer to correct the issue, the issue was not corrected, and the employee reported it to the Michigan Occupational Safety and Health Administration (MIOSHA). If an employee is not reassigned under these circumstances, the employer must pay their wages for the period the condition remains uncorrected. The bill also creates a presumption of employer violation if adverse action is taken against an employee within 90 days of them engaging in these protected activities.
