You can check my employee regularity record for assurance. I would be able to come back after my complete recovery and serve your firm again with the same vigilant and attentive inclination. I hope you take my plea into consideration and allow me to leave for a month. I shall remain thankful for this kindness.

Respected Sir,

With due respect, it is stated that I Rahul Singh have been suffering from severe and sudden back pain that got triggered due to some physical work I did, I guess. I have had a history of back muscle pain throughout my life and it is in a pretty bad condition right now. I have an appointment with my doctor today too to get it checked up so that I can do something about fixing it. Due to these reasons, I consider myself not being able to come to work today as it will just make my condition worse and I don’t think the work will get done too.

So kindly allow me to leave for 2 days. During this period I am hoping this problem will get better and I will be okay. In these 2 days, I will hold my meetings online and will cover all the work I can from home. I will attach my doctor’s report. I will be very thankful.

Thanking you

Yours Faithfully

Rahul Singh
