Exclusiveness of liability.

(1) The liability of an employer prescribed in s. 440.10 shall be exclusive and in place of all other liability, including vicarious liability, of such employer to any third-party tortfeasor and to the employee, the legal representative thereof, husband or wife, parents, dependents, next of kin, and anyone otherwise entitled to recover damages from such employer at law or in admiralty on account of such injury or death, except as follows:

(a) If an employer fails to secure payment of compensation as required by this chapter, an injured employee, or the legal representative thereof in case death results from the injury, may elect to claim compensation under this chapter or to maintain an action at law or in admiralty for damages on account of such injury or death. In such action the defendant may not plead as a defense that the injury was caused by negligence of a fellow employee, that the employee assumed the risk of the employment, or that the injury was due to the comparative negligence of the employee.

(b) When an employer commits an intentional tort that causes the injury or death of the employee. For purposes of this paragraph, an employer’s actions shall be deemed to constitute an intentional tort and not an accident only when the employee proves, by clear and convincing evidence, that:

1. The employer deliberately intended to injure the employee; or

2. The employer engaged in conduct that the employer knew, based on prior similar accidents or on explicit warnings specifically identifying a known danger, was virtually certain to result in injury or death to the employee, and the employee was not aware of the risk because the danger was not apparent and the employer deliberately concealed or misrepresented the danger so as to prevent the employee from exercising informed judgment about whether to perform the work.

The same immunities from liability enjoyed by an employer shall extend as well to each employee of the employer when such employee is acting in furtherance of the employer’s business and the injured employee is entitled to receive benefits under this chapter. Such fellow-employee immunities shall not be applicable to an employee who acts, with respect to a fellow employee, with willful and wanton disregard or unprovoked physical aggression or with gross negligence when such acts result in injury or death or such acts proximately cause such injury or death, nor shall such immunities be applicable to employees of the same employer when each is operating in the furtherance of the employer’s business but they are assigned primarily to unrelated works within private or public employment. The same immunity provisions enjoyed by an employer shall also apply to any sole proprietor, partner, corporate officer or director, supervisor, or other person who in the course and scope of his or her duties acts in a managerial or policymaking capacity and the conduct which caused the alleged injury arose within the course and scope of said managerial or policymaking duties and was not a violation of a law, whether or not a violation was charged, for which the maximum penalty which may be imposed does not exceed 60 days’ imprisonment as set forth in s. 775.082. The immunity from liability provided in this subsection extends to county governments with respect to employees of county constitutional officers whose offices are funded by the board of county commissioners.

(2) The immunity from liability described in subsection (1) shall extend to an employer and to each employee of the employer which uses the services of the employees of a help supply services company, as set forth in North American Industrial Classification System Codes 561320 and 561330, when such employees, whether management or staff, are acting in furtherance of the employer’s business. An employee so engaged by the employer shall be considered a borrowed employee of the employer and, for the purposes of this section, shall be treated as any other employee of the employer. The employer shall be liable for and shall secure the payment of compensation to all such borrowed employees as required in s. 440.10, except when such payment has been secured by the help supply services company.

(3) An employer’s workers’ compensation carrier, service agent, or safety consultant shall not be liable as a third-party tortfeasor to employees of the employer or employees of its subcontractors for assisting the employer and its subcontractors, if any, in carrying out the employer’s rights and responsibilities under this chapter by furnishing any safety inspection, safety consultative service, or other safety service incidental to the workers’ compensation or employers’ liability coverage or to the workers’ compensation or employer’s liability servicing contract. Without limitation, a safety consultant may include an owner, as defined in chapter 713, or an owner’s related, affiliated, or subsidiary companies and the employees of each. The exclusion from liability under this subsection shall not apply in any case in which injury or death is proximately caused by the willful and unprovoked physical aggression, or by the negligent operation of a motor vehicle, by employees, officers, or directors of the employer’s workers’ compensation carrier, service agent, or safety consultant.

(4) Notwithstanding the provisions of s. 624.155, the liability of a carrier to an employee or to anyone entitled to bring suit in the name of the employee shall be as provided in this chapter, which shall be exclusive and in place of all other liability.
