Waiting periods: A period of time an individual must wait to become eligible for benefits for a specific condition(s) after overall coverage has commenced.

Waiver: The giving up of a right or privilege. Nonprofits frequently require participants in recreational or other programs to waive the right to sue in the event of injury. Courts often invalidate waivers on the grounds that the individual did not fully appreciate the rights being waived or that the waiver did not specifically indicate that it covered liability for negligence.

Workers' compensation and employers' liability insurance: The first part, workers' compensaton, covers expenses an employer is mandated to pay by state statute to cover specific benefits for employee injuries. The second part, employers' liability insurance, protects employers from employee-related suits that are separate from workers' compensation claims.
