BALTIMORE (Map, News) - Not only female teachers become their students’ punching bags.

One male teacher at Reginald F. Lewis High, who requested anonymity out of fear of retaliation from students, has filed assault charges against two students who pushed him this school year.

Fights have broken out in his classroom, he says, but when he asks for help from the school office through his classroom’s intercom, no one ever comes.

He tries to take cell phones away, and students say, “Touch my sh--, and I’ll f--- you up,” he says.

He failed 85 percent of his class, but administrators told him the grades would be changed. So he filed a grievance with the Baltimore Teachers Union about his principals, but that’s only brought more pain.

He says his bosses gave him an unsatisfactory evaluation, and he’ll probably be fired at the end of the school year.

“I wouldn’t believe this if I weren’t in it,” he says. “Students corrode any sense of classroom. It’s an impossible situation, and the administration doesn’t do anything about it.”
