Workplace health issues are governed by the Occupational Safety and Health ("OSH") Act, which is overseen by the Occupational Safety and Health Administration ("OSHA"). Nearly all workplace health issues are governed by OSHA or OSHA-approved state programs. Both OSHA workplace health and safety policies and OSHA-approved regulations apply to all public sector employers and all employers covered under the OSH. The overriding principle of the OSHA workplace health and safety program is that employers have a duty protect employees in the workplace from recognized and serious hazards. OSHA works to ensure workplace safety by conducting inspections and employer investigations. When workplace safety issues arise, OSHA has the ability to provide compliance assistance to help employers create a safe and acceptable working environment for their employees.
