It's clear that a wide variety of people are posting their views.
Least qualified of those are the non-aircrew who aren't subject to frequent changes in personal life at ridiculously short notice. They should definitely butt out of the discussion. Their opinions are of absolutely no value whatsoever.
Then we have a group of non-bmi aircrew. If you don't or haven't ever worked for bmi then you have absolutely not the slightest concept of the degree of the problem. What goes on in your airline (and I have experience enough to be able to comment) is just a taster of the sort of thing going on in bmi. So why don't you lot butt out as well. You're doing your bretheren in bmi a disservice by protesting that your life is just fine. Lucky you.
As for evidence of the effects, the disbelievers are obviously not keeping track of the stress related and lifestyle related illnesses on record, nor the effects on divorce rates and resignations.
Basically, lots of waffle out of the tops of lots of hats, as is usual on PPRuNe.
Any, repeat any bmi aircrew (except the inappropriately named management) of more than four or five years experience of the effects of bmi's totally selfish, short-term-penny-pinching (at the cost of pounds) approach will testify to the complete destruction of any decent form of life beyond the time spent slaving to fill the pockets of a few greedy, not to mention lucky (in a business sense), individuals.
So, stand up for yourselves, bmi aircrew and tell them where to stuff their roster disruption.
All bmi have to do is recruit more pilots and get more organised. One costs money, but saves more in the long run, the other.....getting more organised....well....the impossible may take longer!
