Dear Sir/Madam:

It is with deep regret that I tender my resignation from the (provide position and title) effective immediately as provided for under the terms and conditions of employment during the probationary period. In the short time I have been here, I have learnt a lot and I am even in greater awe of the company’s achievements.

I came to this decision painfully after continued deliberations on my part after accepting the offer and concluding that my family needs me more than anything else at this point (or provide other reason). They will be very disappointed of my decision too after having been so supportive of me taking up the offer; but I have strong belief in my conviction that my decision to resign is the bst.

Once more, I thank you and your great organisation for having afforded me this wonderful career opportunity and wish only for its continued growth and success. I will be in touch with our HRD Manager (provide name) to ensure my resignation and actual departure are in keeping with the established company guidelines.

Sincerely,

Name
