I worked for a major carrier for 25 years as a ground engineer and maintenance manager. I went to the cockpit 15 years ago. The major problem the ground engineers have is the turnovers. Many crew member get to the gate or stand and just bitch about their problems instead of explaining it in a civil tone. This set up a bad situtation that is reflected back on all crews. The engineer will go back to the line shack and tell his fellow workers and that's how it starts. It has nothing to do with the life style or pay. In fact, many ground engineers make more money that a F/O.
