Google shuts down Amazon unionization website
The union group may have good cause to sue Google for defamation. Google has the right to terminate their use of Google services.  But for Google to say that unionization information violates their terms of service [1] may be defamatory.  Nothing in the terms of service prohibits this.On top of that, Google's action may violate the National Labor Relations Act.[2] This could be construed as collusion between employers to violate the rights of workers to organize. Google has a record of colluding with other employers to violate labor law, from the famous "anti-poaching agreement".[3]  So Google could have a hard time in court over this, since a pattern of illegal anti-labor activity has already been established.[1] https://www.google.com/intl/en/sites/help/program_policy.htm...
