HR doesn't do anything about retaliation. Bullies get promoted. Classism is rampant. Managers/uppers separate themselves, women managers love to tell you their time is more important that yours because at Google time is based on income. Managers don't attend team dinners/happy hours, but will have drinks with their favorites.
Teammates are encouraged to be competitive beyond healthy competition- CRM and dirty data is composed into story telling that only serves the favorites. For unfavorites, they move goal posts and make imaginary targets so hard to achieve that teammates cheat, throw others under the bus, lie, interfere with others work and get rewarded for it.
Don't take vacation or protected leave unless you want to be fired. Yes, it's illegal but they will find a way and have done so to several people.
With change of administration, "re-org", anyone that shows dissonance, questions decisions, rally union talk, or complains is put on PIP, laid off, or bullied into quitting.
The HR training that is required every so often, is completely disregarded as a task to check off without being followed. Internal surveys are not protected. Managers order pervasive surveillance on employees and punish those that speak up against them or whistle blow.
If a manager has multiple complaints over several years, with substantial legal evidence, he or she might get a long notice and a fat severance offer. The reports/employees complaining will be targeted and forced out, no notice and no severance.
When things are wrong, it's about covering it up- not about making it right with those that have been harmed. HR says the company and employees will never admit wrong doing or apologize. But maybe your class can win a small settlement, eg. Ana Cantu v Google, after going through workplace hell swallowing being blacklisted from any future employment.
***Google, what was once a symbol of forward thinking, inclusion, creating good "for everyone", and leading change through positive rebellion is now just like every other corporate money machine with rightwing extremists, especially within the profitable telecommunications deals with MTU owners and developers.
If you're a terrible person, this is the place for you!
