Forget the bizarre recruitment hoops at easyJet for a moment - most people stagger through them if they are current airline pilots somewhere else. Monarch is full of high quality pilots and no one is disputing that. This is a dark time for those Monarch pilots - be they Captains for FOs. Quite understandably they may look at easyJet as a possible option to secure their future, as indeed it is. Nonetheless, they will also understand that given the fact easyJet have many hundreds of qualified FOs awaiting their turn at the Command Course, the arrival of DECs will not be welcomed. Nor would they be welcomed at BA, Virgin, Thomson or indeed Monarch either. There is a lot easyJet can get away with in Holland because there is no union presence (yet!) to oppose them. However, BALPA is the main game in town within the UK and I do not believe they will sit idly by and watch their own members be stuffed in such circumstances. Therefore this will turn into an almighty fracas, and it is one of the few occasions at easyJet that I can see a ballot for industrial action being successful, if push came to shove. EasyJet can interview anyone it wants for any job - employing them is something else.
Another thing worth bearing in mind is that last year easyJet offered jobs to numerous pilots and then rescinded those offers in favour of employing 155 hour cadets from Oxford and CTC. They did so without awkwardness or embarrassment and would do so again. Therefore, until you have a letter with a start date in your hand, you have absolutely nothing. This is a hard-nosed world and do not be fooled otherwise.
