This is what I suspected and thanks for confirming this. The fact that she wrote that her job is to notify the employees "of employee guidelines and company policies" and chose to withhold the critical bit that it was specifically security policies she was responsible for looks like a deliberate attempt to mislead.

I totally support googlers' right to unionize but it seems that some employees are in an all-out war with the company and think that all is fair in that war. I can't say I support that.
