Most new managers meet this early.
A rep with more years in the field than you. More doctors who know them by name. Sometimes more product knowledge too.
The title on your contract does not settle it. What you do in the first few weeks does.
What I have found works:
- Meet them first, alone, and ask how they see the territory.
- Ask for their advice, and use it where it is good.
- Name what they do well. Out loud, and specifically.
- Agree together how you will work: field days, one-to-ones, updates.
- Remove what slows them down. Samples, stock, approvals.
- On a double visit, ask what they saw before you say what you saw.
And two things that protect the relationship.
- The standards are the same for everyone. Experience earns respect, not an exception.
- If you disagree, do it in private. Never in front of the team.
The mistake I see most often is a new manager trying to prove themselves by correcting the senior rep on the very first field day. It rarely ends well for either of them.
“You do not need more years than them. You need to be useful to them.”
