> Fortunely crushing unions is not a legal in many countries.
Unfortunately, some companies like Amazon seems to simply include "break labor laws" on their balance statements in the end of the year, as they keep breaking the laws in order to save short-term costs.
It works great if the departments don't have a lot of power to stop it. Even if Amazon gets hit with a fine for anti-union behavior, it would be a pittance to their budget, and almost certainly come too late.
As for everyone that gives money to Amazon, and praises their FOSS offerings, this is what evil companies do in practice.
