All states have workers' compensation laws.
The Missouri Workers' Compensation Law is contained in Chapter 287 of the Revised Statutes of Missouri. The workers' compensation statute is the law that controls the rights and obligations of employees and employers when employees are injured at work. Any employer with five or more employees, and all employers in the construction industry, are required to provide protection for their employees under the Missouri Workers' Compensation Law. Most employers do this by purchasing a workers' compensation insurance policy from an insurance company authorized to do business in Missouri. Some employers satisfy their obligation by applying for and becoming qualified to self-insure their workers' compensation liability.
