I used to visit a firm who made a certain article (I shouldnt name it)....they were struggling to keep up with orders and needed say 40 a week. They had never made 40 a week so they asked the workforce..."how can we make 40 a week"......the reply was to pay a bonus for every one over their previous record (whatever that was)....the management agreed and and quite soon they were making 40 a week even if the workforce had to work overtime (unpaid)....pretty soon it was evident that 40 a week was becoming easier so they also agreed that the workfoce could finish for the week once they had done 40......some weeks they were doing this in 3 days and always in 4 days.............So the firm got their numbers, the workforce got paid more and everyone had more time off......Thiis is a true story but unfortunately the firm still closed but it was for reasons beyond their control.My pal was a Construction Manager - on one site the bricky squad used to knock off halfway through Thursday mornings. When queried, their answer was "We've made enough money for the week".
