Did you wake up on Saturday, the morning after your work Christmas party, with the fear? Did you tell the boss where he's going wrong? Busy hands find their way onto the work experience girl's behind? Worry not. We asked our legal expert Tom O'Keefe about the realistic ramifications of overzealous holiday cheer.

Q: Can I really get sacked for having a good time at the office holiday party?

A: Yes, especially if your definition of "having a good time" includes getting wildly drunk, telling your boss how you "really feel," and/or getting jiggy with Jennifer from marketing on top of the printer. Unless you have an employment contract (or collective bargaining agreement) that limits your employer's ability to fire you, you're an "at-will" employee. As such, you can be let go for almost any reason, no matter how unfair you may believe it to be, as long as that reason does not violate the law (i.e., anti-discrimination laws).

But don't think that having an employment contract gives you a free pass to behave like Dionysus -- there are plenty of holiday office party pitfalls (mistletoe abuse) that can provide an employer with requisite "cause" to fire your intoxicated self (consult your office "sexual harassment" policy).

In addition, far too many think that an office party held outside of the office is just "another party." Such people should be pitied, forced to wear safety helmets, and gently led to the nearest unemployment office. The office holiday party is a business event, no matter where it is held, where everything you do, say, drink and dry-hump can be a job killer. This is all especially true in the age of MySpace and Facebook where people can far too easily document your behavior for everyone to see, judge and place in your personnel file.

So behave yourself. Take it easy on the booze, think twice about buying your Secret Santa gift at Ann Summers and stay just long enough to make a good impression or, failing that, no impression at all.

If you need to celebrate the holidays by making a drunken fool of yourself, save it for your buddy's party. After all, that's what friends are for.
