What is the purpose of workers' compensation?

The purpose of workers' compensation is fundamentally to replace income and cover medical expenses for employees who are injured or become ill as a result of their job. This system is designed to ensure that workers receive financial support during their recovery period, without the need to prove fault on the part of their employer. The aim is to provide a safety net for employees, allowing them to focus on their recovery rather than the financial implications of their injury. This compensation typically includes not just medical bills but also partial wage replacement, ensuring that workers are taken care of while they are unable to perform their job duties due to their injuries.

The other options do not align with the primary function of workers' compensation. Providing legal defense for employees does not capture the essence of the program, as workers' compensation is more about support than legalities. Similarly, administering salaries or evaluating job performance does not relate to the protective and compensatory focus of workers' compensation, which is specifically targeted at injuries and illnesses connected to work. Overall, the correct option directly addresses the fundamental goal of the workers' compensation system.
