BALPA's proposal benefits everyone in this scenario. Mainline terms and conditions are infinitely easier to protect and DEPs in OS have a much easier route into mainline when their seniority number permits it. No-one wins long-term if BA get their way with this. It's just the very thin end of a very long wedge that ultimately will see all of our terms and conditions diminished in, I would suggest, all airlines. After all, if BA manage to destroy mainline T and Cs such that top pay skippers earn 50k less than they do now, can anyone see VS sitting back and letting that go unnoticed?
