What happens if a worker from a staffing agency doesn't show up?

Many agencies replace a worker who doesn't show or doesn't work out, and some put it in writing. X3 Tradesmen covers the first 8 hours of a placement with a 100% money-back guarantee, and Precision Workforce backs its placements with an 8-hour satisfaction guarantee. Ask each agency how fast it replaces a no-show and whether you pay for the lost time.
