C32L being so junior is a Bug, not a feature. That BA are spinning it to prospective new joiners as a bonus is them making the best of a bad hand IMHO.
It's (comparatively) poorly paid, and as others have said the lifestyle below about 60% relative seniority is for the most part atrocious. You can make it work, but is it worth the hassle if you're close to a command at a regional base for J2, easy, whoever?
I've heard they might be re running the (internal) numbers for the boeing fleets, to try and squeeze a few more P32 -> P77/P78, but the problem they have is back filling the P32 numbers, as apparently they havent had quite as successful recruitment campaign as they'd hoped. All just rumour, i must add.
