My then gf now wife moved in with me and my employer wouldn’t cover her under the insurance. I made it clear that this was important. They wouldn’t back down. So got a new job. During the exit interview I repeated what I told them. It was only about the health insurance. HR tried to get me to talk smack about my manager, a guy I actually liked. I praised him and again told them that this was only about insurance.

Told my manager about what they did on the way out the door.
