What is a acting role letter?
When a manager goes on leave or leaves suddenly, someone often steps up to keep things running. Acting up is a great development opportunity, but without a letter it can end badly: no extra pay, no end date, and an assumption that the job is now theirs.
This letter confirms the acting role, the reason, the start and expected end dates, the reporting line and the main responsibilities, and what happens to the employee's usual duties. You choose an acting allowance on top of normal pay, the pay of the acting role, or no change. It sets an optional review point, explains how the acting period ends and that the employee returns to their usual role, and makes clear it isn't a permanent promotion — while inviting them to apply if the role is advertised.

Tips before you send it
- Don't let someone carry two full jobs. Decide what happens to their usual duties.
- If the acting period goes on much longer than planned, review the pay and the arrangement.
- Tell the team and other stakeholders who is acting, and from when.
- Use the promotion letter instead if the move is permanent.

Acting role letter: frequently asked questions
Is an acting role a promotion?
No. The letter says the arrangement is temporary and doesn't guarantee a permanent appointment, though the employee is welcome to apply if the role is advertised.
Should acting staff be paid more?
It's common to pay an allowance or the role's rate, especially for longer periods. Some collective agreements or policies require it. The letter lets you choose.
What happens when the acting period ends?
The employee returns to their usual role on their normal terms, and any allowance stops.
Is this the same as a secondment?
No. A secondment usually moves the employee to another organisation or department for a period. An acting role is a temporary step up within the same team or company.
