Samba I’m going to guess that you have never worked for a Uk based charter airline? Random roster all summer with very few weekend days off, night flights, short notice roster changes etc etc.This is commonplace in the UK.
My experience exactly mirrors that of Pumal1w. I guess my username reveals my former employer but I know that other UK charter operators have similar rostering issues.
There are are many things to moan about in RYR but in my experience the fixed roster is definitely not one of them.
Obviously the charter airline summer carnage is mainly a Northern European phenomenon and it may well be that our colleagues in Southern Europe have superior rostering practices. I should also point out that I have been extremely fortunate not to have to commute which obviously results on a more pleasant work/life balance.
