Tennessee Code Title 50. Employer and Employee § 50-6-201

(a)(1) Every injured employee or the injured employee's representative shall, immediately upon the occurrence of an injury, or as soon thereafter as is reasonable and practicable, give or cause to be given to the employer who has no actual notice, written notice of the injury, and the employee shall not be entitled to physician's fees or to any compensation that may have accrued under this chapter, from the date of the accident to the giving of notice, unless it can be shown that the employer had actual knowledge of the accident. No compensation shall be payable under this chapter, unless the written notice is given to the employer within fifteen (15) days after the occurrence of the accident, unless reasonable excuse for failure to give the notice is made to the satisfaction of the tribunal to which the claim for compensation may be presented.

(2) The notice of the occurrence of an accident by the employee required to be given to the employer shall state in plain and simple language the name and address of the employee and the time, place, nature, and cause of the accident resulting in injury or death. The notice shall be signed by the claimant or by some person authorized to sign on the claimant's behalf, or by any one (1) or more of the claimant's dependents if the accident resulted in death to the employee.

(3) No defect or inaccuracy in the notice shall be a bar to compensation, unless the employer can show, to the satisfaction of the workers' compensation judge before which the matter is pending, that the employer was prejudiced by the failure to give the proper notice, and then only to the extent of the prejudice.

(4) The notice shall be given personally to the employer or to the employer's agent or agents having charge of the business at which the injury was sustained by the employee.
