They don't actually work for google at all. Their company does.
They have no rights at all or recourse...this is generally understood when outsourcing to work to subcontracts.
They were fucking morons for going to the city council in the first place. Even more so for saying the word 'google' at any time in the discourse. They work for a sub-par shitstain company, that hires other shitstains, to do shitstain work. As a subcontractor you can be removed without cause, or even for cause - like the cause of "I hate your face".
Crying about your pay and going to city council meetings about it will certainly make a few people hate your face.
