Updated September 2026: in June 2020, after the client's new requirements made two weeks of work redundant, my manager added me to the opportunity to "assist", and the onsite team started addressing all the work to me, although I had no defined role. I have rewritten it into advice on handling being copied in and suddenly treated as the owner.
The client's new requirements meant the previous two weeks' effort was wasted. My manager then looped me back in to support and assist wherever needed. The onsite team read that simple email as a handover and started sending every task to me, though I had no role defined. Then leadership asked my manager for information on existing accounts, and he started acting as though he now owned the whole piece.
Why does "please assist" cause confusion?
Because it does not say who owns what. Recipients fill the gap with assumptions: the new person is taking over, or the manager is stepping back. Everyone acts on a different picture, and work lands on whoever answers first.
What should you do when you are copied in?
- Ask your manager what your role is in one line: owner, contributor or reviewer.
- Reply to the thread with that role, so the onsite team knows too.
- Redirect requests that belong to the owner, politely and with the owner copied.
How do you redirect without seeming unhelpful?
Offer the help you can give while pointing to the owner: "Happy to pull the case studies for this; [owner] is leading the solution slides." That keeps goodwill and keeps the roles clear.
What if you end up owning it anyway?
Then make it official. Ask your manager to confirm the change of ownership in writing, and agree the scope and deadline afresh. Owning work informally, without the authority to decide, is the worst of both positions.
How do you handle a manager who takes over parts unexpectedly?
Clarify the split: which parts they lead, which you lead, who talks to leadership. When a manager takes on a leadership request, it is reasonable for them to own it, as long as everyone knows where their part ends and yours begins.
