Sample leave letter for Grandfather Sickness
Subjects: Leave Application for Grandfather Serious Health
I beg to say that my grandfather is seriously ill. He got a severe heart attack. He is in ICU. The doctor told us to do angiography. His condition is very serious. I want to go home to visit him. My grandfather is the oldest person in my family. It is my first and for most obligation to see him. He is calling me to see him as early as possible. After that, the doctor will take him for operation. I request you to give three days’ leave so that I am able to see him.
I am a good worker at your company so let me go home to see him. I will be grateful if you give me leave for three days.
I look forward to hearing back from you.
Mr. James Watson,
Leave Application for Grandfather not Feeling Well
Rainbow Grammar School,
Subject: Leave request due to the sickness of my grandfather
With due respect, it is stated my grandfather is an old man. His eyesight is very weak. He is not able to see even in the sunlight. You know that it is winter and he has got some problems with joints too. Nowadays, my father is busy in doing office work and will not be able to give time to him.
So I request you to give me leave for two weeks so that I can have time and take care of my grandfather. I shall be thankful to you for this act of kindness.
