I recently went for a promotion having been with my company for a number of years. Unfortunately I was unsuccessful and one of my colleagues who has been with the firm for less than 6months got the role and is now my manager. I feel resentful. I've tried to act professional but I am dreading my first management meeting with them next month. Feel like it's up to them to lead the meeting and ask me how I am doing and offer some opportunities if there are any. Anyone got some wisdom?
