I contracted to install stone veneer according to a sample panel. The Rabbi insisted that I adjust the style. This adjustment cost me substantially more in labor expense than my original bid. I have asked for payment and am being refused. I have invested personal funds to continue the project but have no more money to pay my workers. I have stopped work on the job and am facing possible legal action from the general contractor. There was never a work order presented by myself or the general contractor. There are no clauses in the original contract that deal with "Change Orders". How should I proceed ? Continue to work and invest without guarantee of payment ? Stop work and risk litigation ?
