Tenn. Code § 8-33-104
Any person who is restored to a position in accordance with §§ 8-33-101 - 8-33-108 shall not be discharged from such position without cause within one (1) year after such restoration, and shall, without limiting such person's rights conferred by this or other sections, be considered as having been on furlough or leave of absence during the period of military duty. Such person shall be restored without loss of seniority (including, upon promotion or other advancement following completion of any period of employment required therefor, a seniority date in the advanced position which will place such person ahead of all persons previously junior to such person who advanced to the position during the absence in armed forces). The employee shall also be entitled on reinstatement to participate in insurance (including retirement, pension plans, and medical insurance) and other benefits dependent on length of employment, including vacation privilege and severance pay. The employee shall be protected against reduction in seniority, status, or pay during employment, except as such reduction may be made for all employees whose employment situations are similar.
