Generally, 70-75% of annual leaves in Indian companies go unused, as per a recent report.

Therefore, the leave extension granted to you might be paid or unpaid, depending on your organization’s leave policy.

Tips for Sending Out a Leave Extension

  • Be very professional: The letter must use professional language. Address your manager/ boss and your colleagues professionally. Use appropriate designations. 
  • Wait for the response: The leave is not guaranteed even if the letter is submitted. Wait for a response before taking the extension. 
  • Show gratitude: Always express your gratitude at the end of the leave extension letter. 
  • Highlight the dates: Clearly mention the original duration of your leave along with the start and end dates. Then mention the expected extended date along with the extended duration. 
  • Attach additional documents: Check for any additional documentation required. For sick leaves, a doctor’s certificate or medical reports are required. Procure them beforehand and attach them to the letter. 
  • Addressing your boss: Address the correct person. Some firms require that letters be submitted to HR. Others may require the leave extension letter to be submitted to the manager. 
  • Divide the Workload: Ensure that someone takes up your work. Speak with your colleagues beforehand and arrange for someone to take your place. Mention this in your letter so that everyone is kept in the loop. 
  • Be honest: Clearly state the reason for the extension of leave. Explain your situation briefly. Do not over-explain.
