That's not necessarily a sunk cost fallacy (at least as I understand it). If I add additional charges, the smart thing to do isn't necessarily to fire that contractor. This is because firing them, then hiring a new contractor to finish the job, is possibly more expensive than paying the charges. Asking for more bids, choosing a new contractor, then getting them up to speed can be costly. The rational thing to do would be to weigh your options at that point. Do I believe that a new contractor can get up to speed and finish the project with a smaller budget than the current team?
