I blame the strikers when I have reasons to. When Air France pilots defend the obligatory 60-yo retirement, when Paris transporters defend their privileges and refuse being on par with other public workers (let alone privateers like meself) forming a caste of privileged, well it is them, transporters who are the new oppressor class. Their strike is theirs therefore.

When they refuse being on par with others because of "droits acquis", and when told money not enough, they ask for extra financial revenue taxation, this is politics. Not union work.

The role of the teacher unions is not to support "le service public", but to protect the employees, the teachers. Or they manifest and strike on political reasons that don't affect teachers in any way. They do political work, for political parties.
This is not ok. I wonder if this happens in Germany, for instance (I don't about Italy - those unions are even less true unions and more political than the French ones - purely objectively)
