Best sector to work in?

Cushty? Sitting on your bum doing nowt? I wouldnt like that, nor would many others. It may sound good if youre currently being pushed to work through breaks,but may wear thin after a while.
If youre on a job where you know you can wander off and get exercise, or whatever, can be good, but a job where you have no idea how long you have to wait, can be the pits. As said own account operators tend to pay better, and often give better conditions, as do other more specialized operators. Getting on for one of theses is the target for many of us, but by definition, niche operators arent mainstream, and a little luck is needed to get a start.
