As roles shift, you might find yourself in an awkward situation. If you’re suddenly managing your office friend, it’s time for a mental reboot:
Establish expectations for how you will run things in your new position.
Clarify that all team members will have to follow the same expectations.
Avoid what can come across as favoritism by not gossiping with that friend about things other team members are privy to hear.
Find a confidant in a similar position to you that will understand your situation and be useful during the transition period.
The situation may be out of your control, but your response is not.
