An Act relative to the fair treatment of employees

This bill amends Massachusetts law to prevent employers from discriminating against employees based on their off-duty use of marijuana, provided the use does not occur at work and the employee is not impaired while performing job duties. It explicitly allows employers to take adverse action if an employee cannot maintain necessary professional licenses due to marijuana use or if the employee is charged with a crime related to marijuana. The legislation also permits mandatory drug testing for employers required to do so by federal regulations and establishes a civil legal process where aggrieved employees can seek damages or injunctive relief. Finally, it directs the state's labor and public safety offices to create specific regulations to enforce these new protections.
