Well, the Chinese communist party, which is basically the government. All of us are supposed to be a part of a union; they let foreign tech companies slide for awhile but closed that loophole a couple of years ago.
It is a trade union, but will "work closely with management to resolve any problems in a harmonious way." So not really what you would expect from a union in the west.

Oh, you know, these days in the West, the big unions are more partners with the governments/employers than they are on the side of the workers.
Many unions have become tools that exists only to perpetuate their own existence, instead of being tools for workers to organize and collectively defend their interests against those of their employers and governments.
