I am a retired Police officer, I paid a lot of money towards my pension, that incidently has seen no rise in the past four years and when it does will be linked to the lower CPI rate. There is plenty of medical evidence to show the physical damage and mental stress that more than 20 years of shift work does to a person, that no doubt added to my heart condition. It was not unusual to work 12 to 16hrs shifts often without a break of any kind. Not so long ago the average pension duration was only 3 years before death. I would certainly discourage my children from joining now. There are a lot more easier ways to earn more money.
