An Act relative to employee fairness

This bill amends Massachusetts law to protect employees from being fired or denied hiring solely because they tested positive for marijuana metabolites in their blood or urine. It allows employers to take adverse action only if there is probable cause to believe the employee is currently impaired at work and poses a risk of harm to others, or if the employee holds a professional license that prohibits marijuana use. The legislation explicitly states that these protections do not override any existing federal laws or regulations that employers must follow.
