Who to chase
A short nudge. Assume they are busy, not hostile.
Hi [HR name], I left [Company] as [Role] on [LWD]. Could you share an update on my relieving letter and F&F? I am happy to send any document still pending. Thank you
Set a past last-working-day first — a chase makes sense only after it.
Templates, not legal advice. Match them to your appointment letter before you send.
