So to clarify, both of the female Google employees who lead/organized the protests have now left because they say they faced retaliation. That looks very bad for Google.
EDIT: To clarify, Google's reaction isn't the disqualifier, it's that the employee's action of staging a political walkout isn't legally protected since it conflicts with contractual duties and isn't a typical case of utilizing good faith channels for whistleblowing illegal activity. That type of channel is typically what's protected from retaliation. Not to mention working with someone accused of a crime isn't illegal. Association is a freedom and lobbying to change it is purely political.
Whether the organizers were covered by the NLRA is another matter; those with direct reports are likely excluded by the 'supervisors' exemption, which has been expanded over the years to cover pretty much anyone in a managerial role. For those who are covered, Google's actions could absolutely meet the legal definition of retaliation.
As an aside, the legal standards for what constitutes 'retaliation' are not the only ones that matter. They may manage to avoid a lawsuit, but they will suffer harm to their reputation regardless. I, for one, could not care less whether the law allows them to retaliate against the protest organizers. To me, this is just one in a long line of reasons why I scratched Google off my "short list" of potential employers.
I agree with your aside as well. Public Relations are always in play.
