The hidden problem is that of the experienced pilot who has had multiple redundancies and as a result is a senior FO in his or her 50's. There is simply no recovery from this position as most UK airlines only consider cadets in their 20's and the larger operators arrogantly assume that you screwed up somewhere along the line.
This leaves little option than to look for employment outside of the industry whether you want to or not and is unique to aviation where career progression depends not on experience but only on date of joining or the willingness to pay for a rating and often being under 30 as well.
Sooner or later, this is going to be challenged. Too late for me though.
