Where I came from there was no such thing as a weekend. 24/7 ops as required. None of us likes to work if we think we have time off but I think your tolerance zone is based on what you have been brought up with; what you are used to.
I still feel that a lot of posters in theses pages have led cushy lives. Professional lives are going to get harder, lads and lasses. That is the hard economic truth. Stop thinking that your life is going to get cushier the longer you are on a fleet; you are not going to match the lifestyle (money and time) of those that are substantially up the ladder from you. As soon as you deal with that the sooner you can get on with life instead of fretting about how many weekends you haven't had off.
