The Attorney General’s Office assessed more than $9.6 million in restitution and penalties against employers on behalf of Massachusetts workers in fiscal year 2018.

The AG’s Fair Labor Division conducted every investigation cited in the report; the division is responsible for enforcing laws regulating wages, prevailing wage, minimum wage, earned sick leave and overtime, as well as investigating worker exploitation and wage theft.
