Dear TheoGriff, I have been signed off by GP due to the Work Related Stress. I am going to resign. Question is: in my resignation letter should I mention the reason of leaving? E.g. to say “I wish to confirm that I am resigning my post of maths teacher at … school with effect from 1rs May 2016 due to the Work Related Stress, my last day of employment will thus be 30th April 2016”? Can you advise please? Many thanks!
