I didn't write that that we couldn't, it was about how we could.
For example we shouldn't tell a coworker that he/she's pretty, shouldn't get drunk together, and a lot of behaviour that is considered flirting and getting to know eachother in Switzerland.
In US behaviour outside Google is handled by the company as well, but in Switzerland there are very strict privacy laws and culture that forbid companies to control any part of the life of people outside work. The right to privacy is part of the Swiss constitution, and it's taken there very seriously (to the point where generally the tax authorities don't have the right to look at your bank accounts, unlike in US for example).
Edit: I can't reply, so I extend this comment
,,shouldn't'' is not banning.
And also what you write that Google may have a problem if harassment happens is true, but I still think you think in US law terms: privacy in Switzerland is like voting right in US: it's like telling that ,,you are not advised to vote for Trump as a president''. Or telling you that ,,you are hired, but you should probably go back to Mexico''.
warkdarrior: Again, yes, in US that training is legal and socially acceptable. But the training was in violation of the Swiss constitution...I'm not sure why people in US don't understand that the laws are different in different countries (people from other countries understand it generally). Harassment is a trendy topic right now, but it doesn't trump privacy and the right for not controlling any part of a person's life outside work, even if that's with coworkers, and even if it may lead to a legal problem for Google. In Switzerland people are grownups, they don't need babysitting.
I have to add one more thing: Andy Ruby belongs to prison, everybody knows it, and giving us more trainings won't help the main issue, that the top management was/is raping women or coercing them to have sex to keep their jobs.
