Starting salary within ezy as a second officer is just over £40k. Moan all you want but as a 20 something cadet if you can't live on that I think you've borrowed too much and probably need to review. Grow up, basically.
And there lies the problem. You, like easyJet, have just assumed that an SO is going to be a twenty something cadet with no experience. There is currently no scope for appropriately positioning someone with more experience further up the scale as you and the company just assume everyone comes straight from CTC into the RHS. There are exceptions and they should be treated as such.
With my experience I would suggest that it is not too much to ask to go straight into an FO position at the very least. I know it's only a year in the greater scheme of things but that's still a long time and, coupled with the the fact that LH is part of the endgame, that's why I voted with my feet.
