Ala. Code § 25-5-53
The rights and remedies granted in this chapter to an employee shall exclude all other rights and remedies of the employee, his or her personal representative, parent, dependent, or next of kin, at common law, by statute, or otherwise on account of injury, loss of services, or death. Except as provided in this chapter, no employer shall be held civilly liable for personal injury to or death of the employer's employee, for purposes of this chapter, whose injury or death is due to an accident or to an occupational disease while engaged in the service or business of the employer, the cause of which accident or occupational disease originates in the employment. In addition, immunity from civil liability for all causes of action except those based upon willful conduct shall also extend to the workers' compensation insurance carrier of the employer; to a person, firm, association, trust, fund, or corporation responsible for servicing and payment of workers' compensation claims for the employer; to an officer, director, agent, or employee of the carrier, person, firm, association, trust, fund, or corporation; to a labor union, an official, or representative thereof; to a governmental agency providing occupational safety and health services, or an employee of the agency; and to an officer, director, agent, or employee of the same employer, or his or her personal representative. Nothing in this section shall be construed to relieve a person from criminal prosecution for failure or neglect to perform a duty imposed by law.
For the purpose of this section, a carrier, person, firm, association, trust, fund, or corporation shall include a company or a governmental agency making a safety inspection on behalf of a self-insured employer or its employees and an officer, director, agent, or employee of the company or a governmental agency.
