Stiglet very few airlines are as stable as easyJet I agree. But the job itself is relentless (and arguably tedious) beyond belief at Gatwick, just ask the new guys who've joined easy from other airlines as DEC, many of whom feel they've made the wrong decision.
Don't get me wrong I've enjoyed it here, there's a great bunch of people who make it more bearable but you simply cannot expect to be able to do this for the rest of a 30 year + career now. I'm less than one year in and I've already sussed this out, it is simply far too fatiguing. Balpa are currently in this fight with the company and it is one that simply MUST be won for the very future of this career.
All this is a comment on the industry nowadays rather than necessarily specific to easyJet I concede. But easyJet (with others) are at the forefront of it.
