A snapshot.
Driver A drives for Firstbus.
Driver A was driving a National Express service in an airport, took a wrong turn thinking it was a shortcut and ended up on a live, main runway, with a busload of passengers. He gets sacked, for gross misconduct.
Driver B drives for First Transpennine Express.
Driver B is sick to the back teeth of driving trains with broken horns, which risks the lives of trackworkers. He reports it several times and gets sacked for gross misconduct on a technicality related to a faulty horn report.
So why is one on £20,000 and the other on £37,000 ???
Driver A was sacked, only to receive a call 4 days later from First offering him his job back as they were short. In the event, he had already got a job at Stagecoach the day after.
Driver B was sacked, and will probably never drive a train again, despite never once having a safety of the line incident. He cannot go to another company without totally re-sitting the driver rules & school.
