Obviously you shouldn't trash your boss on Facebook, but that's not the only way social media could hurt your career.  You should also rethink the stuff you "like" . . . your profile pic . . . the email address you're using . . . your privacy settings . . . and the stuff your FRIENDS post.

You already know that you're not supposed to trash your boss or post drunk photos on Facebook.  Here are five ways you're at risk that you're not even thinking about:

1.  If you're "liking" stuff all the time.  It makes it look like you're wasting time, constantly on Facebook clicking the "like" button.  And you probably already know this, but don't "like" anything remotely offensive . . . even if it's a joke.

2.  Your profile pic.  Hiring managers WILL look you up.  And the people they hire generally have well-lit, professional-looking head shots.  Not some blurry, obviously cropped picture from 10 years ago.

3.    You're using one email address for everything.  Don't use a casual sounding personal email address at work or on job applications.

4.  You haven't set strict privacy settings on your account.  You might think all your posts are tame and G-rated, but you still need to lock your account.  If you don't, it makes you look responsible if someone checks.

5.  Be careful of your friends.  You need to be careful about your friend's interactions with you too.  Watch out for them tagging you in inappropriate photos or writing stupid comments on your page.  That makes YOU look bad.  (MSN Living)
