I was there from the Channex days and stayed for over 10 years. I really liked it - up until my last year or two. The training was really good, the rosters, while they weren't 5/4 stable, gave plenty of variety and the pay was great. Ops, rostering and engineering were all fine and even the management were good.
The big change came when they pushed out RB as DFO and replaced him with TWE, the biggest mistake PM ever made IMHO.
Almost overnight the atmosphere changed for the worse. Treatment of staff, particularly pilots, went downhill fast and the race to the bottom started.
Just the fact that a hell of a lot of ex-Jet2 pilots are now to be found in Ryanair tells you all you need to know!
It's a shame, it used to be a great company to work for.
