If you work for a UK major , then most folks there don’t give a stuff about EASA. Its those who generally have plied their trade overseas, wether in Europe or further afield, that have the most to loose.
I know from personal experience, that keeping an IAA licence current while working Outside of Europe, was a simple email with a latest LPC report, sent to the IAA lic dept.
Not so with the CAA licence. Thats why I changed, and will never return.
The CAA is jobs for the old school tie and squadron boys. Old school & irrelevant.
