In my extremely limited experience though (we've probably only had about 30 different bods here at various times working for us - so it's by no means a picture of what goes on everywhere) when they do work, they work. No tea breaks, no stopping to chat, they just get on with it. OK they're away 1.5 to 2 hours for lunch but the moment they come back they're straight back to grafting. When we've been charged for a 35 hour week, we've certainly got 35 hours of work out of them.
