> At dispute here is if this union is even legal in the first place
Does any reputable legal authority think Google's claims have merit here? They're appealing the court ruling against them, sure, but that looks more like a stalling tactic than something they expect to actually succeed.
> Regardless, "bargaining in good faith" purely means an intention to bargain honestly. If that bargain means "nothing changes" - that satisfies the NLRB according to their own website[1].
Which would be a win for the employees - they're trying to get Google's (unilateral, illegal) changes to their working conditions rolled back.
> A union is not a magic ticket to get whatever you want. Employers are free to reject any demand for any reason. Being an employee does not mean you can force an employer to give you things...
Not true. Employers have obligations, employees have rights, and unionised employees have more rights. Yes, you can't always get everything you want. But you can get some things, such as preventing your employer from unilaterally worsening your working conditions.
