Good tech is easy to spot hes the one who kicks himself more than any manager ever could.Bad tech the one who will perform just enough to keep manager off his butt.Watch people they are easy to figure out.Even good techs have problems with customers,Not so much tech as billing why ist this this but the manager has to take care of all that plus.Good employees always show themselfs.My problem was Id wear a good man out and just abide with what ever else I had to to fill work spots.
