Resignation letters can be designed in many types dependng upon the circumstances that lead to resignation. Any resignation letter shoud be sent in advance either one month's notice or 3 months's notice to enble the organization/Company to make alternate arrangements. As for as Government sector is concerned, the resignation letter must contain the reasons for resignation and also self declararation to the effect that the resignation is tendering with sound state of mind and health and without pressure of any other on this. One such format, in a simple manner, I am giving hereunder:
(Head of the Organization/Company)
Due to some unavoidable circumstances on personal reasons, I hereby tender my resignation to the post of ( name of the post) with effect from (date) in the organization ( Name of the organization)
I hereby declare that I am in sound state of mind and I am fully aware of the consequences out of my resignation. I also declare that I am not giving this resignation out of any pressure on me on any side .
I request the authorities kindly to accept my resignation with effect from (date)
Thanking you Sir,
