If you are looking to resign from your current position because you have found another job that you are looking to take, then you need to write a detailed letter resigning from your current role. Before doing so you need to refer to your contract of employment and find out what your notice period is in accordance with your terms and conditions.
If you are handing your notice in with immediate effect and this is not in accordance with your terms and conditions then you will need to have a good reason for this and be able to explain it to your employers.
If you are looking for some help in writing this letter please see the below example which you may use as a guide.
Resignation Letter with Immediate Effect
Resignation from the role of XXXX
Please accept this letter as my formal resignation from my JOB TITLE with immediate effect.
I understand that this is not in accordance with my terms and conditions of employment, however I have very little choice because of REASONS (think carefully what these reasons are, new job and they won’t wait for you to start won’t wash, family illness etc maybe).
I am very sorry to be leaving you in a position where you do not have anyone doing this role however I feel that I have left my duties in a good order and will spend today helping you to make sense of anything that you need to know.
I would be grateful if you would forward my final pay slip and P45 to my address (as above or detail here where you would like it sending to). I understand that my final pay will include any holiday pay that I have not taken and any monies owing for the work that I have done to date.
I would finally like to thank you for the experience you have given me working with COMPANY NAME and I would like to wish you all the very best of success for the future. I feel that COMPANY NAME has a very bright future and I am sorry that I am not going to be part of that.
