Don't know what the Google management is thinking at this point in time. But I'm damn sure, unless you are making it rain hundreds of millions in dollars, and you are a part of these pre-unionizing exercises- You are very likely getting marked up as a trouble maker, and may be already a part of purge lists.
This is also a small industry. You don't want your name to smeared as a person who comes with a high trouble/contribution ratio. Nobody wants to hire people to do their jobs, and get employees running their part time political projects with their fellow colleagues in paid office time, on office issues.
There are also a huge range legal landmines you are likely to step over even without active knowledge that you are.
