How's this for a resignation letter? Tempted to put a "Go fuck yourself and your job" in it somewhere but probably wouldn't be the best idea.
Dear xxx
I am writing to inform you that I am resigning from my position as xxx at xxx. I will fulfil my four weeks’ notice meaning my last shift will be on Thursday the 8th August.
After nearly two years I feel it’s time to move on. I have appreciated my time here and feel like I've developed numerous career skills that will aid my future job prospects.
Thank you for your professionalism and I wish you the very best of luck in the future.
Yours Sincerely
