It is not false. It is not true for all unions, but it is true for some.

Management is NOT your enemy. This is probably the worst lie unions keep repeating. The best solutions are win-win. Yes management has different interests, but that doesn't make them an enemy.

Fundamentally, why do we work? We work for money. The employees want to make as much money as possible, the employer wants to make as much as possible. Management, representing capital, can make more money by paying their employees less. Therein lies the fundamental, unsolvable conflict between labor and management.

There are win win solutions to that conflict which makes it solvable.

By the company as a whole making more money, everyone can make more money. But no matter how much more money the company makes, capital and by extension management can make more money by paying the employees less.
