I live in France, in most companies you don't get to finish your trial period if you are out of the office.
However for a low pay job like this one, you don't get a 3x2 mnth trial.
You also need to understand something about French healthcare : money is where the risk is. Our Intensive care services are amazing, however basic depts are not that great.
I don't think we should compare the taxi lobby to an union. French politicians are scared of them for one reason : they keep talking about politics to their clients. Violence isn't a such a nice way to get what you want.
