Yeah thinking about it more, you’re definitely right. I’ve only ever been a W-2 employee (United States) so I know nothing about this kind of thing. If they are employees of another company, they should bargain with them instead, and force them (via strike if required) to negotiate a new contract with Google. I’m very pro worker and support striking to get results but you have to make sure you’re targeting the right business to get the results you want.
