T he days of holiday office party photocopying disasters are long gone. Today's image savvy employees steer clear of the Xerox machine and try to avoid being part of the gossip circuit. But Ottawa hasn't been immune to layoffs and downsizing in the face of tough economic times and many may want to let loose this season. To help you maintain a professional image in the digital era of Facebook and Twitter, etiquette specialist Julie Blais Comeau gives these do's and don'ts of partying with colleagues this holiday.

1. Going solo or with a guest

It's important to read the invitation. Not doing so could be embarrassing, stressful, downright rude and an unexpected expense for your host. When in doubt ask the party co-ordinator. If the invitation only has your name on it, you go solo. There are no exceptions to this one. If it states your name and guest you have the choice of going solo or with a guest. If you choose the latter, prep your guest info about your work mates and make sure to introduce him or her to all that you mingle with.

2. Dress Codes: Don't show too much skin and don't bling like a Christmas tree.

Remember the key word is holiday office party. You are still a representative of your employer during this activity. Follow the dress code indicated on the invitation or ask. Generally, for an after-hours celebration, maintain your daytime dress code and add one festive accessory such as suspenders, a tie and jewelry or dress in holiday colours. Save the holiday cardigans and sexy tops for celebrations with loved ones.

3. Drinking, dancing and singing ... in moderation

Keep the conversation light and positive. As a rule, when mixing business and pleasure at a social gathering, limiting your alcohol intake to two drinks is probably wise. If your boss is paying for music or karaoke, participate and keep it G-rated.

4. When a colleague is over the limit.

If a close colleague has displayed inappropriate behaviour and has personally upset you while intoxicated, keep your cool and make sure the person has a safe ride home. Address the situation when you return to work and speak to him or her in private to make sure it doesn't happen again. If you are not close to that person, don't go there; let a superior or someone in human resources take care of it.

5. Texting, tweeting or tagging. Don't immortalize any celebration photos.

First rule of thumb: Think. If your grandma wouldn't approve, don't do it. When you get to the office party your techno gadgets should not be visible and in silent mode. Your Bluetooth's red flashing light is not a holiday accessory. Should you choose to take photos, ask permission first, make sure they represent your employer well and do not post the images until you have reviewed them again at work. The same goes for tagging, writing on someone's wall, tweeting or commenting.
