I think the relevant test is here: "Kathryn Spiers, who worked as a security engineer, updated an internal Chrome browser extension so that each time Google employees visited the website of IRI Consultants — the Troy, Michigan, firm that Google hired this year amid a groundswell of labor activism at the company — they would see a pop-up message that read: “Googlers have the right to participate in protected concerted activities.”" It sounds like the person updated an internal extension on everyone's computer to do this. I am tending to side with Google on this, that is not the right way to go about notifying co-workers of right to organize.
