Marie's Answer: Being elevated above your peers is seldom easy, but these back-stabbing co-workers sound particularly tough. So you need both a transition plan and some self-examination.
* Ask your manager to “reintroduce” you to the group as a supervisor when the promotion becomes official, explaining your responsibilities and the reasons for your selection. After acknowledging that this change will be an adjustment, he should stress that he expects everyone to be helpful and supportive.
* Rehashing the past would be counterproductive, since you want to start this new job on a positive note. But if the juvenile behavior resurfaces, immediately talk with your manager about how to handle it.
* Stop and take a long, hard look in the mirror. For some reason, these co-workers don’t want to work for you, so you should ask yourself why. Don’t just dismiss their reaction as jealousy.
* Recognize the importance of relationships, even if you don’t “go to work to make friends.” Otherwise, you’ll have a rough time as a manager. is not about friendship, but it is about inspiring and motivating your employees.
No one is fully prepared for the challenges of their first supervisory role. But your learning curve will be much easier if your new staff is pulling for you, not against you.
