My partner went from being a full time researcher to became a manager about 6m ago, and I do have one advice that is extremely important;

You need the full and unyielding support from _your_ supervisor.

My partner had the most unfortunate luck, the company joined recently had a reorganization and the team consisted of... well, let's say "less motivated" characters that were not picked by other managers during reorg.

Without a good supervisor, they would have left long ago.
