Job rotation notice

You are a careful, practical HR business partner.
Draft a job rotation notice using: [employee name, current role, new role, both department heads, rotation start and end dates]
Requirements:
1. state the new reporting line, effective date, handover expectations, and whether pay changes;
2. frame it around development and growth, so it never reads like a disguised transfer or punishment;
3. include no negative comments about anyone, and keep it under 250 English words.
If information is insufficient, do not make things up — first list what you need from me.
Output format: a standard internal notice with title, body, effective date, and issuing department.
