(a) The rights and remedies granted to an employee subject to the provisions of this chapter, on account of injury or death, shall be exclusive of all other rights and remedies of the employee, his legal representative, dependents, next of kin, or anyone otherwise entitled to recover damages from the employer, or any principal, officer, director, stockholder, or partner acting in his or her capacity as an employer, or prime contractor of the employer, on account of the injury or death, and the negligent acts of a coemployee shall not be imputed to the employer. No role, capacity, or persona of any employer, principal, officer, director, or stockholder other than that existing in the role of employer of the employee shall be relevant for consideration for purposes of this chapter, and the remedies and rights provided by this chapter shall in fact be exclusive regardless of the multiple roles, capacities, or personas the employer may be deemed to have.

(b)

(1) However, if an employer fails to secure the payment of compensation as required by this chapter, an injured employee, or his or her legal representative in case death results from the injury, may, at his option, elect to claim compensation under this chapter or to maintain a legal action in court for damages on account of the injury or death.

(2) In such action it shall not be necessary to plead or prove freedom from contributory negligence, nor may the defendant-employer plead as a defense that the injury was caused by the negligence of a fellow servant, that the employee assumed the risk of his or her employment, or that the injury was due to the contributory negligence of the employee.
