Why wait to develop a bad relationship with the new boss? Try these five stunts and get things moving downhill from the get-go.

These career-killers come courtesy of leadership and development manager Dan McCarthy, who writes the blog for GreatLeadershipByDan.com:

1. Assume the worst about your new manager. Expect that he/she is evil, a liar and a backstabber – and behave accordingly. Don’t give new managers the benefit of the doubt.

2. If you have good information that you think will help the manager, keep it to yourself. Let the boss make mistakes and fumble around for a while. It’s the best way to learn. Plus, you’ll be entertained by it all.

3. If the boss suggests new ways of doing things, hold fast to the old ways. Fight change like it’s death. Believe that it’s up to the new boss to change and adjust to you, and not the other way around.

4. Got a bunch of grievances about your job, your employer, your old boss? Unload them immediately on the new boss. It’s good for the soul. Better yet: If you know of others who have grievances, drop them on the boss, too, just to show you’re a leader.

5. Disagree with the new boss every chance you get, especially in front of others but also don’t miss a chance to do it behind the boss’s back. Get extra credit by not just disagreeing, but also by correcting the boss.

5a. Keep your résumé up to date. You’re going to need it.
