Indefinite Leave Letter for Work Due to Sickness (Sample)

Some diseases are not curable in a short span of time. It may take months or years to be cured. In some unfortunate cases, these kinds of sickness may not be cured especially in diseases like cancer. However, the way science is advancing, a person should always keep his hopes high.

An employee can become gravely ill and his treatment may prolong for an indefinite period. He should intimate his employer by letter or email as soon as possible. He should seek leave for an indefinite period explaining the reasons for it.

Whether or not the employer will allow such an indefinite leave is a different issue. No human could be so unkind to a sick person in such severe cases.

Following leave letter format is for your reference.

Sub.: Request for leave from work due to my illness.

Dear Sir/Madam,

I am hereby applying for a leave from work for an indefinite period because of the serious nature of my sickness. I am sorry to inform you that I am suffering from (Name of the Disease). My doctors have advised me to start getting the treatment immediately. Hence, I am going to be hospitalized from (Date) onwards for treatment.

I am enclosing a copy of the medical test report for your kind information. As you might be aware, such a sickness takes a lot of time for treatment and recovery, whereas the chance of being fully cured is sadly a questionable thing. As such, I am not sure how long I am going to be on leave from work for this treatment.

Therefore, I kindly request you to approve my leave for an indefinite period. I will be keeping you updated on the progress from time to time if you do not mind. As soon as I get better and in a position to work, I will join back at service.

Looking forward to your support now at this juncture of my life.

Thanking you,

Yours sincerely,
