CLINTON, Tenn. (AP) - A former worker at Anderson County's alternative school has filed a grievance with the state Department of Education alleging that special education students are illegally isolated.

The Knoxville News Sentinel reports (http://bit.ly/RqzpJ9) Dale Martin said in his complaint that he was a member of a three-person crisis team at The Learn Center from 2004-2012.

Martin lists 28 special education students that he contends were isolated. He says three students were put in a room more than 20 times each and one student placed in isolation more than 50 times.

Martin said he chose to retire last year because of the hostile work environment he had to endure for refusing to isolate students.

Anderson County's Director of Special Education Sue Voskamp said the allegations were false.
