Under Massachusetts law, if an individual is unable to earn full wages for five or more full or partial calendar days due to a work-related injury or illness, an employer must report the injury to its insurance carrier within five business days. Once reported, the insurer has 14 calendar days to either start paying benefits or notify the individual in writing that the claim is being denied. As a workers' compensation attorney, I ensure that these deadlines are met, and if not, I seek to hold insurance companies accountable when they do not comply with the law.
