In argentina, unions are constitutionally protected. Union leaders are defacto politicians, as they cannot be arrested for many crimes without congress approval. What is unique about argentina is that unions are right-wing and shut the left-wing parties out. And the left parties (socialist, communist) always denounce that the unions are constantly selling off the workers.
Today, the strongest union leader is getting indicted because it used union's funds to sustain his own soccer club.
Bravo, well said. Solid working conditions, meaningful employee input to company decision making processes, and excellent remuneration for all doesn't really impact the bottom line but significantly improves quality and productivity in most cases.
German unions are less antagonistic because they are required by law to get representation on the boards of all companies with more than 500 employees.
