A workplace injury is an injury or illness that occurs in relation to an employee’s job. Most states narrow the definition of a workplace injury to one that “arises out of and in the course of employment” to prevent employees from pursuing compensation for injuries not directly caused by the job. Generally, a workplace injury occurs because the work environment is unsafe (the premises are dangerous, the equipment is defective, or the environment is contaminated with hazardous chemicals). In addition, jobs that require repetitive or difficult movements (eg. factory labor or heavy lifting) may cause injury.
