Frequently Asked Questions about Sample Letter for Interim Position

Do I need a formal letter for a short interim role?

Yes, even for roles under 30 days. A written letter eliminates assumptions about authority and responsibilities. It also creates an official record for HR and payroll.

Should an interim position letter mention pay adjustments?

Always include compensation changes explicitly. Never rely on verbal agreements for pay. This prevents payroll errors and avoids misunderstanding with the employee.

Who should sign an interim position letter?

The letter should be signed by someone with formal hiring authority, typically a department head or HR representative. Never send this letter from a peer or team member.

Can an interim position be ended early?

Yes, but this should be stated explicitly in the appointment letter. Include a 3 working day notice period for early termination to avoid unfair surprise.

Should I share this letter with the whole team?

Always circulate a redacted version of the letter to the full team. This confirms the appointment for everyone and removes confusion about who is leading.

What happens if someone declines an interim role?

Employees may decline interim appointments without penalty. Never pressure staff into temporary additional responsibilities. Simply move to the next suitable candidate.

Do interim roles count toward promotion eligibility?

Most organisations count successful interim assignments towards promotion consideration. State this explicitly in the letter if applicable to encourage good performance.

Should I include limits to authority in the letter?

Always list both granted authorities and explicit limits. This prevents overreach and gives the interim employee clear boundaries for decision making.

How far in advance should I send this letter?

Send the formal letter at least 5 working days before the start date. This gives the employee time to ask questions and prepare for the role.

Every interim assignment comes with inherent uncertainty. A clear, detailed letter removes that uncertainty before anyone steps into the temporary role. Take the extra 10 minutes to draft this document properly, rather than fixing avoidable problems later.
