Worker Rights OSH Act Occupational Safety and Health Act (OSH Act): Signed into law December 29, 1970 Entitles workers to safe and healthful conditions Provides workers with the right to: Ask OSHA to inspect their workplace Review employers records of work-related injuries and illnesses Get copies of their medical records Receive information and training about hazards and their prevention, using applicable OSHA standards. School of Basic Pharmaceutical and Toxicological Sciences Undergraduate Toxicology Program
Worker Rights OSH Act - continued Worker complaint: Workers have the right and may file a complaint against their employer with OSHA Employers may not retaliate (take unfavorable personnel actions) against an employee for being a whistleblower. For more information, please see: OSHA Whistleblowers Protection Program Whistleblower laws require that complaints be filed with OSHA within 30 calendar days following the alleged retaliation.
