Personally I cannot equate to all the negative comments about Jet2. Too many people with axes to grind I think. The Company is not perfect (show me one that is) but there is a genuine effort to improve things and progress. Standards are high (maybe that is some people's problem?) and virtually all the people I meet and fly with are high quality and excellent company from both a personal and professional perspective.
If you don't like it go somewhere else - you spend too long working to be so bitter and twisted!
