Even if your work environment is relaxed, maintain professional composure when around your co-workers. Here are four habits you should avoid at the office:
1. Being too optimistic. If people at your work are trying to handle a crisis, it undermines their professionalism when you chime in that their crisis isn’t that critical.
2. Flightiness. People need to know they can depend on you to get things done. Don’t flake out on responsibilities.
3. Keeping secrets. When something is relevant to the issue at hand you should let your colleagues know. Keeping secrets will make people question how much they trust you.
4. Overpromising. Don’t make promises you can’t keep. Promise the most that you can while still being able to achieve it.
