BEWARE OF WORK NO-NO'S

Everyone's got plenty of advice on what you should do in order to keep your job, but what workplace mistakes should you avoid?

WHAT NOT TO DO

Some things are obvious: Excessive office flirting. Looking for another job on your office computer. Talking back to your boss. But are there things you're doing at work that could actually get you fired?
BNET lists "10 Things You Should Never Do at Work," outlining the types of behaviors that could spell trouble for you if you're planning on moving up the company ladder.

Social media

For example, don't say or type anything that could get you in hot water. Some of us are so frequently sending emails, posting to social media sites like Facebook and Twitter, or watching random cat videos that we forget our office computers are keeping track of everything we're doing.
Posting photos from last night's party on Facebook while you're at your office desk? Better not. Tweeting how boring the meeting you're in is -- while sitting at the table with your coworkers? Not a good idea. Privacy at work is pretty much nil. You're better off pretending you're the star of a reality TV show, and everything you're doing at the office is being broadcast for the world to see.

Relationships

Other work don'ts include: obsessively using your mobile phone to text, talk with your friends, or keep up with your online circle; over-committing and under-delivering (you're almost always better off doing the reverse); and trash-talking to your coworkers.
To that, we'd add that being overly competitive can hurt you. Companies work best when workers work together, and managers looking to promote you are keeping an eye on whether or not you can get along with your peers and if you're capable when it comes to sharing your skills with others.
At work, don't be that reality TV-show girl who declares, "I'm not here to make friends!" It won't help you, your career or your company.
