Sorry??? Fuuuuuuccccckkkkk that oldfart – best move you'll ever make. Good on you, anyone coming on here to knock you will likely be jealous and stuck in a shittty job wishing they had the cajones to do th same as you.
Welll done man, enjoy your freedom.
Day I left I felt the same mix of emotions but suspect this was cos I was leaving good mates rather than an under appreciatd, under rewarded, tiring job. Ps if you feel you can't stomach another round of industrial action then I think you deserve a break after 27 years.
