I am going to take early retirement at the age of 58, due to the crucifying workload and stress of my current position (bullying by SLT). This is not something I ever planned to do, but have got to the sad position where I doubt I will ever want to teach again. With this in mind, how should I word my resignation letter? I obviously won’t be using this as a means to vent my spleen, but feel uncomfortable at having to produce a gushing letter just to appease the powers that be. Can anyone advise please?
