it is a cage here, you are right. all they want is, that you work, family, your interests, friends are another thing.
i do not mind working, not at all, but at least give something back - if you want something from rostering it is 100% not possible unless you go to your chief pilot, ask for permission - takes too much effort and too much time
on the other hand, if they want something from you, you have to do it, without asking - if you ask, you will get in trouble sooner or later.
and to you foreveryoung: obviously nobody briefed you, that they do not want to hear the truth or be yourself - be honest
anyway, i think you will not miss it
good luck with your career
