The title is
technically accurate, but I think the omission of scale and any sense of how far along these plans are leaves quite a sensationalist tidbit. "Google workers announce plans to unionize" translated to "the necessary amount of employees at Google to form a union are unionizing" on my first pass. I clicked immediately because that seemed significant. I'm sure this was the intention, though I can only speculate. A clear and less sensationalist (though less click-worthy) title could have been as simple as: "230 Google workers announce plans to unionize"
That being said, I'm not contesting the validity of the movement - it's certainly possible that thousands of Googlers will sign on in support now that the movement is public, and more power to them!
It just seems like the reporting on this should be making it more clear where this effort stands and just how much needs to happen before it's legally viable. Arguably, more honest reporting in that regard would help make clear to potential allies that their support is needed, and this is not a sure thing.
