Not an export on US law but apparently Civil Rights Act of 1964 "... forbids discrimination when it comes to any aspect of employment, including hiring, firing, pay, job assignments, promotions, layoff, training, fringe benefits, and any other term or condition of employment."
And applies to any organisation doing significant amounts of cross state trade, or having more that 15 employees. So Google's probably covered.
