In Denmark if a political decision is taken that is against the union, the union can start a counter strike against them. Have happened before and it set the country on breake.
I know that but the gouvernement could passes law and unions couldn't do nothing about it (that's what happen when a gouvernement uses force instead of dialogue). In the recent years the French gouvernement passed many laws that weakened employees rights. Do you know that if you go into court against your employer and you win, you will just get few hundred euros? It won't ever cover for lawyer expenses. That's because a law was to max the amount you can and it is very low.
Yes I know but the French gouvernement passed many laws not in favor of employees. There were strikes for months but the gouvernement didn't listen and police was beating people.
Now an employer can fire you because of race / sexual orientation... Etc. You can win if you went into trial but the employer may pay just few hundreds euros because there is a limit that caps how much the employer will pay.
