And what you forget, NO JACKETS REQUIRED, is that other departments, including the pilots, have been changing their Ts & Cs and pay for several years - unlike the cabin crew. BASSA have harumphed, foot-stomped, hissy-fitted and more for years, and now the change that should have been made long ago, in small increments, is going to be made in one fell swoop.
Of course its going to hurt, but BASSA has only itself to blame. Market forces and a lousy financial period are going to claim those who wander around with their fingers in their ears and blinkers on their eyes. Bad luck.
