Tom work out 25% of whatthey do and work it out to an hourly rate. Or just simply pay 25% of what is done. Putting them on a price gets more done in the long run.
25% of what they do ? LOL !!! At that rate they could undercut you by 50% and double their wage !! Hang on, maybe i'm wrong and its possible to sit at home earning 75% of what an employee takes.
Why?? It works out between £8-10 an hour. If any of them tried to undercut me of screw me over id simply knock ten tonnes of poope out of them however this hasnt happened so i must be doing something right hey??.
I take it you would spend years building up a good reliable business, employ someone and pay 75% and mug yourself off.
Get real man 25% is more than reasonable.
