How Much Would You Turn Down To Leave Google?

Google GOOG has stepped up from its $100k bonuses last summer to offering one of its engineers $6 million for not leaving the company to work for Facebook, according to Business Insider. Last week Google offered $3.5 million to an employee, and has almost doubled that this week in the form of a stock grant. These stock options and bonuses are certainly nice for those receiving them, but surely Google may face troubles in the future when these large offerings become expected, especially if employees purposely seek out opportunities at other companies just to get a rise out of Google management.
