I 100% guarantee you don't know that this would be the case. If the correct way is penalties then the correct course of action for the subcontractor would be to try to not get caught, there are penalties for union busting tactics already, and that is not stopping them. It would be easy for google to do things to make it clear that they do not oppose unions: Steve Gyrgo has worked with HCL for two years. He says he is not against unions as a whole, but he is worried that after forming a union, Google might want to work with another contracting firm. Google can just put out a press release that says that union shops are welcome to be google subcontractors and that they as a company will have minimum compensation guidelines for subcontractors to show they are committed to people being fairly compensated for their work.
