Tennessee Code Title 50. Employer and Employee § 50-1-312

(1) “Employee” means a natural person who performs services for an employer for valuable consideration and who possesses a valid handgun carry permit recognized in this state; and

(2) “Employer” means a person, association, or legal or commercial entity receiving services from an employee and, in return, giving compensation of any kind to the employee.

(2) In any action brought pursuant to this section, the employee shall have the burden of establishing a prima facie case of discharge, or adverse employment action, based solely on the employee's transporting or storing a firearm or firearm ammunition in the employer's parking area in a manner consistent with § 39-17-1313(a). If the employee satisfies this burden, the burden shall then be on the employer to produce evidence that one (1) or more legitimate reasons existed for the employee's discharge or adverse employment action. The burden on the employer is one of production and not persuasion. If the employer produces such evidence, the presumption of discharge, or adverse employment action, raised by the employee's prima facie case is rebutted, and the burden shifts to the employee to demonstrate that the reason given by the employer was not the true reason for the employee's discharge, or adverse employment action, and that the stated reason was a pretext for discharge or adverse employment action. The allocations of burdens of proof set out in this subdivision (b)(2) shall apply at all stages of the proceedings, including motions for summary judgment. The employee at all times retains the burden of persuading the trier of fact that the employee has been the victim of discharge, or adverse employment action, based solely on the employee's adherence with § 39-17-1313(a).

(3) The employee has one (1) year from the date of termination of employment, or the date of adverse employment action, to file an action pursuant to this section.
