Tammy Ferry, an employee of Jefferson City Public Schools, has filed a lawsuit against JCPS as of Monday.
ABC 17 News first reported about the planned filing in March.
Ferry claims to be the victim of sex and age discrimination.
Less than a year ago, a jury ruled in favor of a similar lawsuit filed by Karen Ray, who claimed that she was bullied and forced out of her job.
Ferry testified in that case, in which Ray was awarded $225,000 in punitive damages.
Ferry’s lawsuit claims that the retaliation by administrators got worse after her testimony in May 2016.
