You always behave well around your boss, but how well do you mind your manners when you are around your coworkers? There could be spies among them, so make sure you are being good today. You should definitely avoid getting involved in any idle office gossip. Steer clear of people who just love to complain, but hate to offer suggestions on how to make things better. Changing your attitude is easy when you realize that a better attitude equals a better career.
