Not in my experience. As a disclaimer, you can play it either way. But it my last job, the boss had a reputation for being hot-headed, and he had people that disliked him. But I never had a problem with him. He didn't go off unless he had a valid reason. Things have to be done a certain way.
He got me in his sights once or twice. but even before he started in, I knew exactly what he was going to say, and why, and I knew he was right.
