The rights and remedies granted in this article shall exclude all other rights and remedies of an employee, his personal representative, parent, surviving spouse, dependents, or next of kin, at common law, by statute, contract, or otherwise on account of the contraction of an occupational disease, as defined in this article, and on account of any injury, disability, loss of service, or death resulting from an occupational disease, as defined in this article. Except as provided in this article, no employer included within the terms of this chapter and no officer, director, agent, servant, or employee of such employer shall be held civilly liable for the contraction of an occupational disease, as defined in this article, or for injury, disability, loss of service, or death of any employee due to an occupational disease while engaged in the service or business of the employer, the cause of which occupational disease originates in the employment; but nothing in this section shall be construed to relieve any person from criminal prosecution for failure or neglect to perform any duty imposed by law. The immunity from civil liability shall extend to any workers' compensation insurance carrier of such employer and to any officer, director, agent, servant, or employee of such carrier, and such immunity shall further extend to any labor union, or any official or representative thereof, making a safety inspection for the benefit of the employer or the employees.
