NHS Resignation Letter Example
1st June 2014
Dear Miss Turner
I have decided that the changes in the Trust are not what I anticipated when I commenced in this role. Having searched for alternative employment I have recently been offered a post for a private firm.
I am therefore handing in my notice with immediate effect. I have calculated that my last working day will be 1st July.
I have really enjoyed working within this team and am grateful for all of the training and opportunities I have been offered in this post. I would be happy to assist with training any new staff and will provide any information required to hand over my caseload to the incoming staff.
