Moses,
Protect the current crew from suffering too much future financial loss
Bizarrely enough, right back when, at the start of this mess, the company wasn't going to cut wages at all, new fleet was up for discussion between BASSA and the company and the only detriment to the Cabin Crew was the removal of one member on the aircraft.
When BASSA refused, steadfastly, to negotiate, claimed ridiculous cost savings on a temporary basis and threw a hissy fit at having to share discussions with other CC Unions they refused to negotiate further, thus the company imposed changes that were required to implement an emergency business plan.
Throughout this it has been BASSA that have been intransigent, beligerent and childish, not the individual crew members, many of whom have been caught up in the cross fire.
BASSA are the problem, with their small minority of militant members with the loudest shout.
I remember the rigs well! Hated those landing pads in the night! Long live the bears.
