Which of the following actions would have negative consequences if you choose to accept a management promotion?

a.

be prepared to review the keys to being a good manager

b.

be prepared to learn your new responsibilities

c.

be prepared to treat your coworkers in the same way you always have

d.

be prepared to prove that you are the best fit for the job

The correct answer is letter C: Be prepared to treat your coworkers in the same way you always have.

Treating coworkers the same way you always have after accepting a management promotion would have negative consequences because receiving a promotion comes with more responsibilities in many areas and it also means you will be the boss of coworkers that you previously worked with. Treating them like you are still on certain position or giving them the trust to act the same way towards you may bring negative consequences in the future, mostly in situations were you need to "Be a boss". If your coworkers feel comfortable with you, there may occur situations were they will expect flexibility and this can also bring issues to you as a boss.
