(You've asked an extraordinarily odd question. There's a context in which such a question might imply that the OP should look to God and religious texts for guidance rather than rely on their own reason, but I'm going to go out on a limb and guess that you're not suggesting that the bible/Koran/Baghavad Gita/whatever offers words on the matter of Google employees and their relationship with their employer that supersede human judgement.)
