The liability of an employer prescribed in Alaska Stat. § 23.30.045 is exclusive and in place of all other liability of the employer and any fellow employee to the employee, the employee’s legal representative, husband or wife, parents, dependents, next of kin, and anyone otherwise entitled to recover damages from the employer or fellow employee at law or in admiralty on account of the injury or death. The liability of the employer is exclusive even if the employee’s claim is barred under Alaska Stat. § 23.30.022. However, if an employer fails to secure payment of compensation as required by this chapter, an injured employee or the employee’s legal representative in case death results from the injury may elect to claim compensation under this chapter, or to maintain an action against the employer at law or in admiralty for damages on account of the injury or death. In that action, the defendant may not plead as a defense that the injury was caused by the negligence of a fellow servant, or that the employee assumed the risk of the employment, or that the injury was due to the contributory negligence of the employee. In this section, “employer” includes, in addition to the meaning given in Alaska Stat. § 23.30.395, a person who, under Alaska Stat. § 23.30.045(a), is liable for or potentially liable for securing payment of compensation.
