Write email to manager for leave request

Subject: Request for Vacation Leave

Dear [Manager's Name],

I am writing to request a vacation leave for the period of [start date] to [end date]. I have been working diligently on my projects and I believe that a vacation will help me refresh and come back with renewed energy.

I have made arrangements for my work to be covered during my absence, [colleague's name or department] will be handling my responsibilities during this period. I will ensure that all my pending tasks are completed before my departure and I will make sure to provide all the necessary information and instructions to [colleague's name or department] to ensure a smooth transition.

I will also be available on email and phone in case of any urgent matter. Please let me know if there are any further details or documentation that are required for my leave application. I look forward to hearing back from you and thank you for your time and consideration.

Best regards, 

[Your Name]
