These posts make grim reading. It may be worth summarising why BA pilot T&Cs fell so far so quickly (IMHO). It would seem that the previous BACC prioritised keeping all BA pilots on the same seniority list and resisting any plans to set up a low cost BA operation at LHR. They achieved these aims and the rapid growth in BA pilot numbers and commands is the reward. The downsides are numerous as so much was sacrificed along the way; the introduction of a B pay scale, the loss of a final salary pension, SH working to EASA rules and perhaps worse of all, the erosion and eventual loss of BidLine. Numerous other quality of life measures were also given up. A BA manager famously remarked that the "BACC were far more effective at controlling pilot costs than BA management."
Anyone contemplating joining BA should seek as much advice as possible from mates on the inside. In particular anyone aged about 40 or over should seriously think through their likely career path. A first LH command aged 55+ and the consequent severe deterioration in lifestyle may not be a realistic option when the opportunity finally arises.
Anyone living more than about 2 hours journey from LHR should also think carefully. BA are focusing on commuting time for a number of reasons. BA pilot fatigue reports have increased by a factor of 40 since EASA rules were implemented and are likely to rocket far higher if the new JSS rosters are anything like the trial runs. BA will examine whether commuting time was a significant factor in generating fatigue, they would much rather we all lived in Slough or Staines and travelled in by bus (reducing their never ending car park issues).
Sadly it is no longer a "happy" place to work and that is unlikely to change.
