1. Brag about salary . If your new job has resulted in a significant pay in crease , that's good for you . However, it's rude and inappropriate to share that information with your now co-worker . So keep your happy yo yourself,.remaining tight-lipped may help you avoid resentment and necessary strife. 2.Bad -mouth your former employer . it's not OK to speak poorly of your former employer . This will leave a bad impressive on your workmates. Even if you worked for the worst company ,and you still harbor some resentment ,you need keep quiet about your true feelings. Gossip is just not classy . 3.Express desperation . Even if you were on the brink of losing your home and you just finished clearing out your life savings before getting the job, don't let everyone in the office know that . Oversharing is unprofessional . it maight even cause others treat you poorly because they will know that you would do anything to keep your job because you're in bind . 4. Spend half the day decorating your new space . you are moving into a new office , not a new apartment.don't start arranging chair pillows . Being too concerned with how space looks show that your focus is in the wrong place.
