Well, I want no taxation without representation, literally! Public transportation is financed from taxes. People who take jobs there must have some obligations, like I do to my employer. Why they should decide whether I should go to work or pay so much for taxi, if it's available at all? If those people working on public transport are not happy, I do understand them... But please announce everything in advance, not the Charlie Foxtrot situation that happened a year ago.
I don't know how it is in France, but where I live public transportation strikes are announced at least more than a week before they happen.
Last time, it was announced in advance, but for weeks if not months no one knew when it would end.
