Not all workers have a union. And the current trend in Hungary is to take away more and more workers rights. A law is quite toothless if it's not implemented that way.

Example for workers rights: Currently unemployed people get benefits for some time and after that the state will employ them (see közmunka) for less than minimum wage. In practice, what happens is that some companies previously employed workers with minimum wage, let them go and re-employed them for a lower wage via the state. This in turn creates an incentive to keep those workers in this perpetual state, because it's less desirable to employ them directly. (And no, they don't get any more money from the state or anything to match the loss of wage)
