Transport workers had a range of financial advantages that no one else had in France, except maybe parliamentarians. Calling this privileges is a common sense statement precisely reflecting the reality. This is a caste of privileged, compared to the rest of the workers. Considering their "droits acquis" normal and speaking about virtual paycuts (curious expression, does it translate in a virtual reduction of the size of their lunch, or in giving up a virtual toy for their virtual kids) is typical leftwing propaganda.
I can't give you specifics at the detailed level you imply, and you know that. Not because they do not exist, but because I cannot comment simultaneously on inequalities, socially-imposed gender roles, history, religion, working conditions today, nurses, French unions.
You'll soon find an essay on my diary explaining in detail my view on society, with all its different aspects. The fact that you don't have it here and now, is solely because this debate here is about inequality and gender roles, and when one has 240 posts, one needs to focus one's discourse. This doesn't "frame" that person as not serious, superficial, ignorant, or political propagandist. You may always say it, but it ain't so. Free at last! Free at last!
