Being a hard-nose boss is not a strength, it's a weakness (although he might not see it that way). I use to have a manager that was tough and raised her voice to bark out orders. I use to call her "The tough Dove", but not to her face.

Tough on the outside, soft on the inside. She tried to be tough to hide her weakness. People managers that get their employees to work because they like them are showing strength. If you can step away and view them in that light, it makes working with them a little less frustrating.
