Hi - I am resigning from my teaching post and am not sure which date to put on the letter of resignation. I want to resign at the end of the spring term, before the start of summer. Advice on here generally states the 30th April as the date to use but my school will have started their summer term then. The last day of school in the spring term is 9th April and the first day back in summer is 23rd April. I am confused as to which date to put. Any advice appreciated.
