Marie’s Answer: The peer-to-boss transition is always tough, but you can take comfort in the fact that many people have made it successfully. Here are some steps that may help:
• Meet with Ellen and Terry to openly discuss the change. Acknowledge that moving out of familiar roles is difficult and ask what they have found challenging about this transition.
• Explain that your primary goal is to be an effective manager. Ask what traits they feel are important in a supervisor, then describe your own views. This will help to establish you in the manager role without any heavy-handed proclamations.
• Use the authority of your position in a mature, professional manner to end the disruptive behaviors. This is an absolutely critical skill that some managers never master.
• For example, when chatty Terry launches into a gossip session, politely stop her and explain that you have a lot of work to do. If aggressive Ellen attempts to hijack your instructions, just smile and say "Ellen, I’m not quite finished with what I was saying." Then continue talking. They will quickly get the message.
New supervisors almost always suffer from “imposter syndrome” at first, but before too long your role should feel much more comfortable.
