Back of an envelope calculations

Last week my driver on Leeds 180 commented that he had done 60 traffic duties at Crich this year and still had a few to do in October. We then speculated that the national minimum wage would be about £50 per day so that, had he been an employee, he would have earned at least £3,000. The cost to the Museum would be in the region of £4,500 to account for NI, holiday pay, pension contributions etc.
The Museum is open for over 200 days a year and the minimum staffing requirement is an inspector, 2 drivers and 2 conductors. Multiplying this up we arrived at a wage bill of £250 per day x 200 = £50,000 + additional costs = £75,000 per year for a minimum two car tram service.
I have only done 16 conductor duties but these have saved the Museum £1,200.

Glasgow 22 and Leeds 180 were the service trams again yesterday. An ideal combination for the time of year.
