The entire public sector, including state employees and some private sector workers, is covered by the Massachusetts State Plan.
Furthermore, employees designated as or employed under Federal OSHA Jurisdiction are not protected by the Massachusetts State Plan. All federal employees, including those employed by the USPS and civilian staff on military facilities, are subject to OSHA regulations. All of the authoritative responsibilities of the Massachusetts State Plan continue to be under the oversight, inspection, and modification of OSHA. Further, Massachusetts State Plan has initial penalty enforcement authority but Federal OSHA retains the authority to fine businesses and employers for OSHA violations.
