Automotive HS principal Caterina Lafergola exiled to a stinky former bathroom two black teachers she wanted to fire — an incident that insiders say exemplifies her history of leadership abuses.

Lafergola, who is leaving the Williamsburg, Brooklyn, high school for Long Island, ordered teachers Maureen Allen and Yvonne Davis-Henry to spend their workdays in the grimy, foul-smelling room after slapping them with termination charges.

“It was a deliberate attempt to dehumanize us,” Allen told The Post, crying as she recalled the ordeal.

“We were locked in there like monkeys.”

Allen and Davis-Henry described the small room as dirty, with cracked tiles, mold and an odor seeping through pipes where a toilet and sink were removed. There was an old desk with a broken computer.

Lafergola dismissed a series of black staffers in her four years as principal.

Lafergola did not return an e-mail seeking comment. The DOE said it closed a probe of Lafergola’s actions because a “complainant” did not contact investigators.
