As a lowly TP driver who's been in the pool for quite a while...
I'm not bothered by rated people getting start dates ahead of me. It makes absolute sense for BA to take as many rated people as they can, as they'll be on the line far quicker.
I'm not bothered by guys with less hours than me but with a bit of jet time getting long-haul slots. Someone, somewhere has decided that the limit for those types is x amount of jet hours. That's cool. I can very much understand the frustrations of those on the A320 fleet that may be denied the opportunity to move on however.
I'm not bothered with on-going recruitment - there are a lot of seats to fill across all types.
What bothers me is the real possibility that after doing my very best to pass each stage of the assessment process, being told that 'there are jobs for all' and that 'nobody will get left behind', that I will not get to join BA after all. That really, really worries me.
