Gym Teacher Claims He Was Fired for Being Straight, Having Family

Says athletic director biased in favor of younger women with no children

A married, heterosexual gym teacher at a tony Upper West Side private school was fired because his lesbian supervisor disapproved of his "traditional family status," the canned teacher claims in a new Manhattan lawsuit.

Gregory Kenney, 50, taught gym at the Trinity School on W. 91st St. for 16 years before he was let go in June 2012.

Kenney, who lives with his wife and three young children in LI, says he was a well-liked employee at the elite institution that counts Truman Capote, Ivanka Trump and Eric Schneiderman as alumni, until a gay athletic director named Pat Krieger took over in 2009.

Krieger allegedly forced him to coach three sports, even though his contract only required him to join two teams, according to his reverse discrimination suit.
