Get active! Agitate! At least actively propose and defend all suggestions towards the betterment of working people. The establishment thrives on passivity.
I do wonder how effective this would be if for example a multinational can simply withdraw from Belgium or even the EU :-( Even if the argument was made that it was more efficient or at least not less efficient than the status quo, a lot of these companies have a very heavy US-biased view on work-life-balance (see for for example the current RTO initiatives as well).
Their plan is definitely to leave locations where working conditions are not in their favor. Not so lol for the people losing their jobs, though right? :-(
