I didn't feel like apologizing to an employee I snapped at, so I didn't.
Wait, what? Why didn't you apologize?
I think she's too retarded to know what's happening.
You don't sound like a very nice boss. When you are in the wrong, you should always apologize. You'll find that your employees will like you more.
I'm a perfectly nice boss. It's not like I hit her.
Employees can be annoying, but if you snap at your employees and don't apologize, they are going to quit. Try being a more considerate boss if you don't want to keep having to hire new people.
