Don’t overdo it at the cocktail table

This might be the first time your boss gets to see your “other side”. The last thing you want to do is cast yourself in an unprofessional light by downing too many drinks before leading the sales department through a slurred rendition of “Rudolph the Red-Nosed Reindeer”. Don’t get caught up in the festivities and start acting like you’re back at the frat house.

Dress appropriately

Sure, it’s OK to stray from the business-casual wardrobe that outfits you day in and day out throughout the year. But you’re not going “clubbing”. Let your typical office attire be your gauge. It’s fine to lean a little less conservative, but not too far. While office parties are festive events, standard workplace behavior is expected.

Don’t try to “hook up” at your work party

If you’ve been waiting for the chance to see the “hottie” down the hall in a more social setting, remember who’s watching. Use the party as a chance to engage in mature conversation to get to know somebody a little better. But tales of the couple who were caught making out in the coat closet will do nothing to improve your standing with upper-management.

Don’t complain if your Christmas bonus was low or non-existent this year

Times are tough. Many companies are even skipping the festivities due to expenses. If you’re overheard grumbling about not getting a big, fat Christmas bonus (or, for that matter, about anything else negative toward the company) words can travel fast. Keep them to yourself and enjoy the party. Not everybody is getting one these days.

Don’t just blow it off

Your office party probably hasn’t been advertised as being mandatory, but treat it as such. Go, at least for a while. If you’ve already got a prior engagement, be sure your office manager is aware of it ahead of time. To ignore it without acknowledging it would be disrespectful.

Remember: The best rule of thumb is do not detach yourself completely from office norms that dictate your everyday behavior at work. Stay in good standing with your superiors by obeying these rules of etiquette.
