Been doing it for nearly 6 years now Its all i've ever done since leaving school. 7am - 7pm, 7pm - 7am at my last job and now i'm doing 11pm till 7am during week days and 7pm to 7am at the weekends. Usually have some time off in between working nightshifts and dayshifts so its not that bad.... i enjoy it, gives me plenty of time off Plus more money
