It's a general reply. The idea of being picked on might have something to do with the fact that there is a reason for it?
If I were you I would look at pushing the union into accepting a good hourly rate, some changes in lateness credit and disruption agreements. In return you should be pushing for a similar bidding system as flight crew have. Thereby earning you transparency and have a modicum of freedom over where you want to go and have an influence over the days you are working etc etc.
Change is inevitable. You might aswell box smart and get something really tangible in return.
