An injury that occurs while an employee is on the clock, performing work-related tasks can be covered by workman’s comp insurance. Exceptions to coverage could apply if the injury occurred off-duty, such as during the commute to work, or if the employee was under the influence of an illegal substance when the injury occurred. Chronic injuries, such as carpal tunnel, workers’ comp may also apply. It is critical that the employee provide as much documentation as possible so that they can prove that the injury was indeed directly caused by work-related duties. The specific work compensation law regarding non-covered injuries will vary from state to state.
