So we are really just a big cup?

Dog software running on furry hardware.

Not my experience.

In my job they are trying to do something similar (AI driven productivity control) and unions are fighting against it.

Pretty much it. Unless there’s an infringement of labor law. I don’t know where they work or much about other countries labor laws.

They would probably need to hire a lawyer in this case. Unions usually also help in these cases.

This is the reason Unions exist.

Individually you have no power. As a group you do have power to force them to revoke these decisions.

Your choice is joining a Union or not.
