It is a discriminatory or unfair employment practice for an employer to terminate the employment of an employee due to that employee's engaging in any use of tobacco products off the premises of the employer during nonworking hours unless such a restriction: (1) Relates to a bona fide occupational requirement and is reasonably and rationally related to the employment activities and responsibilities of a particular employee or a particular group of employees, rather than to all employees of the employer; or (2) Is necessary to avoid a conflict of interest with any responsibilities to the employer or the appearance of such a conflict of interest. Notwithstanding any other provisions of this chapter, the sole remedy for any person claiming to be aggrieved by a discriminatory or unfair employment practice as defined in this section shall be as follows: the person may bring a civil suit for damages in circuit court and may sue for all wages and benefits which have been due up to and including the date of the judgment had the discriminatory or unfair employment practice not occurred. However, nothing in this section may be construed to relieve such person from the obligation to mitigate damages. It is not a discriminatory or unfair employment practice pursuant to this section for an employer to offer, impose or have in effect a health or life insurance policy that makes distinctions between employees for the type of coverage or the cost of coverage based upon the employees' use of tobacco products. The provisions of this section shall not apply to full-time firefighters.
