Unless a union contract, or the individual's contract of hire, requires it, an employer does not have to hold an injured worker's job open while they are unable to work due to an occupational accident. MGL c. 152 § 75A does require employers to give preferential treatment in the rehiring of injured workers when they are ready to return to work. MGL c. 152 § 75B requires that employers make all reasonable accommodations to anyone who is deemed to be a qualified handicapped person under MGL c. 151B.
