This certainly sounds unfair, but not necessarily unlawful.  There are no laws in Tennesee that specifically prohibit retaliation, bullying or targeting in general. There are specific laws that prohibit some of this conduct in specific situations. For example, if you are bullied or target due to a factor such as sex or race, you could have a claim for unlawful sex or race based harassment.  Additionally, if you were retaliated against for a legally protected activity such as using FMLA or requesting workers compensation, then such act might be unlawful. Otherwise, Tennessee is an employment-at-will state where an employee can be fired for good, bad or no reason at all.
