Im phasing back to work in public sector having been out on sick leave for 8 months. I'm not keen on the thoughts of working a 5 day week. I had gotten used to being on half pay while I was out sick. The idea of a shorter working week appeals to me but wonder would a 4 day week or a 3 day week be worthwhile from a tax view.Im 56 and need to work 3 full years before I can qualify for full pension. Salary is 45k.
