do we have any construction science people here? if so, my question is this.... what if you we're co-managing a job site and like ordering stuff and things and the guy that you were co-managing it with started flaking out and tweeting weird things about his gf and then after a long day of driving around and ordering and measuring stuff he says that he's done and doesn't want to hammer stuff and talk to plumbers any more with you and quits. then he tries to come back a week later. would you take him back? would you allow him to drive to home depot in your truck and stuff or not? i guess that's my question.
