There are things you should never say to your boss if you want to keep your job. How many of these have you heard co-workers say? How many of them have you said in the heat of the moment?

Here are the 10 things you should never say to your boss:

1. "Impossible. Can't be done."

2. Complain about how cheap the company is.

3. "Not my problem."

4. "That isn't in my job description."

5. "Does it really matter if I get this done?"

6. "That's a no-brainer."

7. "I just followed you on Twitter."

8. "I got so trashed last night."

9. "I don't get paid enough for this."

10. "Sigh."
