Interesting to think about which labour and tax laws will apply to the employers, since the moon(1) or outer space(2) is not under the jurisdiction of any nation. Not to mention that Google is a company and the treaties applicable are agreements between states ;)

For those really interested probably US Law does apply since Google INC. is a US Corporation and therefore the law of the employer does apply...
