Litebulbs,
It does not make financial sense to over recruit M/F crew and have any crew sitting at home whatever contract they are on.
BA have also made a commitment NOT to do this and are able to time training courses for new starters to coincide with crew leaving. BA have the ability to offer rest day working on all fleets including M/F and temporary part-time increases or decreases on WW and E/F in periods when they are under crewed or over crewed and they already currently use these methods to adjust crewing levels rather than taking on too many new entrants as you suggest.
It really is just a Bassa scare tactic to suggest WW or E/F will sit at home on their supposedly huge!! salaries and do nothing. It just would not make financial sense particularly as the offer includes guaranteed variable pay also on top of our salaries!! The whole point of all these changes is to make crew MORE productive not less, so leaving us sitting at home really does make NO sense at all!!
