"The Respondents have a quite complicated payment mechanism for the different types of employee. We were only concerned with the mechanisms for the inspectors of whom there were five in all. The broad method of calculation is set out for example in Mr Saffery's witness statement at paragraph 12 showing that over each block of eight working weeks there was a calculation of the 'lost hours' the 'clocked hours' and the 'yield hours' which produces a multiplier in a detailed fraction. That multiplier in turn is averaged out over a 24 week period and applied to a base hourly rate at the time fixed at£8.40 . That resulted in an actual hourly rate of some two to three times that base hourly rate depending on the particular figures and percentages."
