What does "playing Devil's advocate" mean?

Thanks that clears up so much. I hear it all the time and now I can finally say it myself and look like a knowledgeable boss. :D Thank you!

You are welcome ^_^

The term is also sometimes used for people who advise their friends to be selfish and morally incorrect, The devils advocate does not do bad stuff, but he advises others to do so. Often humorously, so he cannot even be blamed. Or he might point out why an immoral/unfair way to act would be more profitable.

For example, if my friend comes to me asking advice about how to motivate her employees and I tell her to fire all the unhappy people, I am playing the devils advocate.
