I once ran out of an ASDA store when I saw 'Back to School' signs up. I almost collided with a colleague. Give us a break, please! It was at least 2 weeks before I was fit to go on holiday in the Summer - and I started having the stress dreams and working 2 weeks before return.
The colleague I mentioned spent 2 years having repeated breakdowns, but they would not let him retire. I left early (on medical advice) to save my sanity and health, but lost massively on my pension, which is now pathetic.
