So labor unions are not left wing? Is that what you are saying?
The Polish labor unions fought for the freedom of Poland in the 70’s & 80’s.

Lech Walesa was a hero back then and it was THAT movement the Pope endorsed. IIRC, the Pope was from Poland.
Those unions may have been “left wing” relative to the ruling totalitarians but they were in this case on the right side.
