you treat it like an emergency, get coverage now, notify the client, document everything, then hold the sub to the contract on no show fees or losses. because every idle hour burns crew pay, material time windows, and client trust, and acting fast limits the damage. first call the sub and their lead to confirm whether it's a real no show or a short delay and get a firm ETA. if they can't commit, send the fastest safe option you have, either an in house crew or your backup sub, and tell the client the revised plan and timing. take timestamps, photos, and save texts and call logs so you can invoice a no show fee or deduct labor if the contract allows. after the job, score the vendor in your log and restrict future work if they miss again, because letting repeats slide costs whole jobs. how are you handling no shows now and what one rule would you lock in to stop the same gap from happening again?
