I don't think it's something that they consider relevant. It's how it is, take it or leave (it).....
Personally, I believe that whilst pilots can be recruited and rolled off the production line, pilot welfare is way down on the list of things to do. Should that situation change, then you may see improvements in the day to day life of pilots.
Rosters delivered just days before you need them, minimum rest between duties, alternating days/nights and single days off have been the norm for so long now. If management had the inclination to change anything they would have done by now.....
