Do not expect any kind of social responsibility in AB. You are an exchangable 3LC, not more, not less. They do not care about the health of the pilots.
Fatigue risk management is only written in the books, in real life it is not existant.
Just to give you an example. The office guys (working from Monday to Friday, heated office, fixed hours, no weather influcence, no walking on apron at -20 degrees) have been offered events for stress and burn out prevention. That is the guys who create the nice rosters with 7 working days for pilots, in that 7 days of course you start early (earlier than the first flight in from whereever you live), have a night duty to end after 167 hours, most likely there is no flight to whereever you live).
Commuting is only possible if you live in one of the scandinavian countries, all others are not working.
Any kind of flexible roster as 20/10 will never happen, they do not like it but of course they will promise you "we are working on that".
Trust only informations which are written.
Vacation, not plannable, you will know if you can go worst case 2 weeks in advance. In theory you can add off days to vacation days, in real life you end with a duty period of 7 days after your last vacation day.
Who ever is able to leave will do. Reason: roster, roster, roster, roster.
