Here are 10 tips to help you improving your rapport and become a better co-worker:
1. Keep it down. Whether it’s singing to the radio, or slamming file drawers, reduce the volume of noises.

2. Don’t your burn bridges. The single most important thing to remember is to be considerate. If you think about how your behavior impacts others, you will understand how to behave courteously.

3. Avoid office politics (Part I). When the resident gossip “confides” insider information to you and is waiting to hear your reaction and rebuttal, don’t bite no matter how tempting. “You won’t believe what the receptionist told me…” Scandalous scuttlebutt flourishes on the office grapevine and you don’t want it to come back to haunt you.

4. Clean up after yourself. Make sure you clear the kitchen, bathroom, don’t leave food in the fridge, etc.

5. Silence. Avoid annoying phone ring tones or computer sound effects. While you may enjoy hearing “It’s a Small World After All” over and over every time your BlackBerry rings, you can bet you’re the only one.

6. Cut clutter. Make sure your thriving collection of plants doesn’t cascade over into adjoining areas.

7. Avoid office politics (Part I). Today’s politically polarized environment makes discussing even the most innocuous issue a potential touchstone for office controversy. So keep your opinions of politics and religion under your hat.

8. Temper your toxicity. Try not to let your personal life affect your office professionalism. Co-workers will cringe at your ability to put a negative spin on things.

9. Good hygiene. Oftentimes, you’re with colleagues at the office than you are with your family at home. That doesn’t mean you should become complacent in your grooming. Your co-workers will always appreciate your use of shampoo, soap, deodorant, toothpaste, etc. Spraying cologne/perfume doesn’t help you smell fresh/clean.

10. Short breaks. By all means share a quick story at the coffeemaker that will brighten someones day. But don’t run out and kill an hour smoking while the boss is away.

The best environments to work in are those where people get along and have built friendships. It is in both your best interest and the best interest of the company to maintain a cooperative, friendly work environment.
