What has made google look at the facts and think this is the right way to proceed? Do they think this won't blow up? Do they fear unions so much that this is worth the bad PR? Or is this just a corporate process that no-one took a big picture view on? Because from where I am standing, this just seems like a dumb move.
The game, as I understand it,^ is a "yes or no" game. Either Google unionisers get a union or they don't. If they do, what that means will be be worked out later.
So yes, Google plausibly don't want a union (or a big union discussion) enough to take chances with bad PR, or labour court. Totally different scales of threat.
^not well.
