Link here. This memo clarifies for everyone what is expected of Google employees. I especially find this quote informative:
Please remember, as you no doubt read in the Employee Handbook, Google’s commitment to diversity is complete and unequivocal. Any variance from diversity is not permitted and will be dealt with immediately. It is only when all of us think exactly the same thoughts that we can achieve perfect diversity.
Of course, Google is also completely committed to the advancement of science and human knowledge. If history has taught us anything, it is that science can only flourish where the allowable topics of discussion are highly circumscribed. Approved subjects of conversation are posted throughout the campus, so please look before you speak.
I believe some of the problem lately has been a simple misunderstanding of my last memo. Unfortunately, I mistyped that Google “approves of free speech.” I meant to write that Google must “approve free speech.” I want all of our employees to feel perfectly free to express themselves however their political, moral, or religious beliefs impel them; provided of course that they receive prior written authorization.
Read it all. It really explains everything.
