Worker's Compensation is a form of insurance providing wage replacement and medical benefits to employees injured in the course of employment in exchange for mandatory relinquishment of the employee's right to sue their employer for the tort of negligence. The trade-off between assured, limited coverage and lack of recourse outside the worker compensation system is known as "the compensation bargain". One of the problems that the compensation bargain solved is the problem of employers becoming insolvent as a result of high damage awards. The system of collective liability was created to prevent that, and thus to ensure the security of compensation to the workers. Individual immunity is the necessary corollary to collective liability.
While plans differ among jurisdictions, provision can be made for weekly payments in place of wages (functioning in this case as a form of disability insurance), compensation for economic loss (past and future), reimbursement or payment of medical and like expenses (functioning in this case as a form of health insurance), and benefits payable to the dependents of workers killed during employment.
General damage for pain and suffering, and punitive damages for employer negligence are generally not available in workers' compensation plans, and negligence is generally not an issue in the case. These laws were first enacted in Europe and Oceania, with the United States following shortly thereafter.
