MUNCIE, Ind. – An Indiana teacher who lost his job for “poor classroom management” is suing his former school, alleging he was actually terminated because he’s very fat, and that’s against the law.

Muncie Area Career Center Teacher Tim Crehan filed a federal lawsuit against Muncie Community Schools Oct. 27 alleging the district violated the Americans with Disabilities Act when they fired him about two years ago – in October 2013, The Star Press reports.

Muncie Teachers Association President Pat Kennedy told the news site the union wasn’t involved with the lawsuit, but did fight to help him fight his evaluation with the school board that ultimately showed he met performance expectations in his teacher evaluation.

Crehan is now using the teacher evaluation as evidence that he was allegedly fired for the wrong reasons. The school board approved Crehan’s termination Oct. 10, 2013 in a 4-1 vote based on “poor classroom management,” “neglect of duty,” and “not meeting performance improvement plans,” according to the news site.

In the lawsuit, Crehan attempts to explain away several incidents that occurred in his classroom.

“In the claim, Crehan specifically responds to allegations that during class one student burned another student and, in a separate incident, that one student consumed alcohol and became intoxicated,” according to The Star Press.

Crehan contends that because students could bring food and drinks in their bags to class, and because teachers supervise multiple classes, “many negative school behaviors go unobserved by teaching staff,” according to the lawsuit.

He claims he was not made aware that the student who burned his classmate was already a convicted felon, otherwise he would have kept a closer eye on the student.

“Therefore, the lawsuit says Crehan believes he was fired because he is morbidly obese, which is in violation of the Americans with Disabilities Act,” the news site reports.

Crehan wants his job back, as well as damages for lost pay and benefits over the last three years.

The news site does not detail Crehan’s weight, but he’s certainly not the first teacher to claim they were canned for being fat.

New York teacher Michael D. Frank sued the Lawrence School District after he was fired in 2004 after years of glowing performance evaluations. Frank was about 6-foot 4-inches tall and 325 pounds at the time.

“Despite more than a dozen ‘overwhelmingly positive’ reviews from four supervisors over the years, he said his fortunes changed abruptly in February 2003,” according to the Big Fat Blog.

In that case, Frank’s attorney argued “obesity is a medical condition protected under the Americans With Disabilities Act and New York State human-rights laws,” though it’s unclear how the case was ultimately resolved.

In 2007, child care worker Lisa Harrison was also allegedly fired for being too fat. Harrison complained to the Equal Opportunity Employment Commission but died in 2009, before the case was resolved, NOLA.com reports.

Harrison was morbidly obese at about 5-foot 2-inches tall and 400 pounds.

The EEOC pursued that case posthumously, and eventually reached a $125,000 settlement with the nonprofit she worked for.

Jim Sacher, regional attorney of the EEOC’s Houston district office, issued a statement after the case was resolved in 2012, BusinessInsurance.com reports.

“Employers cannot rely on unfounded prejudices and assumptions about the capabilities of severely obese individuals. Despite performing her job for years, Ms. Harrison was terminated without warning and without any evidence that she could not perform the essential functions of her position. The case highlights the fact that severely obese people who can do their jobs are every bit as protected by the ADA as people with any other qualifying disability,” Sacher said.
