So, when company, factory owner, or who sell service/good get together, and talk how much they will charge consumer, it is price fixing.
So, I just thinking, worker are those who sell larbor. Worker band together, which we call worker union, to decide how much they should ask from their employer, seem similar to price fixing.
Let me put it in business terms.
It is a contract. A labour agreement between an employer and a group of employees who have every right to democratically agree on some things like pay.
It lays out expectations with responsibilities and ramifications for both sides and provides a stable term once an agreement is made.
It prevents price fixing by an employer in the sense that a lone employee can have their ‘price’ fixed by the employer and their roles ‘fixed’ by the employer with no power to fight back as a lone person against at least a company lawyer. An employee in a union with a collective agreement has counterweight to abuse because they too can pool resources, they too can cause harm to the other side and fight back, and it works - because it’s a contract.
