At least in my state (MA) a while ago being fired with cause means not eligible for unemployment[1]. I knew this from someone (last century) being fired for being overheard quoting "office space" the movie on the phone, and therefor suspected of being dangerous. He was not given a chance to defend himself, but hated the job anyway.

"PETER Boy. I tell ya, one of these days... One of these days it's gonna be like

He mimics a machine gun. Brian, a waiter, does it too, in Peter's face."

He went to hearing to get his unemployment, and won because the layer from bigco, sent to the hearing from out of state literally wouldn't answer any questions.
