Office of Investigations
The DIA Office of Investigations is responsible for ensuring that all employers operating in the Commonwealth carry workers' compensation insurance at all times, pursuant to MGL c. 152 Section 25A and Section 25C. Any employer that is found to be in violation of the statute shall be served with a Stop Work Order (SWO). The SWO requires the business to close immediately upon service of the SWO and carries a fine of $100 per day until the employer presents proof of a valid policy and pays the fine.
