Full text copy of Memorandum OM 12-59, the latest report on social media in the workplace issued by the National Labor Relations Board General Counsel on May 30, 2012. From the report's introduction:

"Employee use of social media as it relates to the workplace continues to increase, raising various concerns by employers, and in turn, resulting in employers’ drafting new and/or revising existing policies and rules to address these concerns. These policies and rules cover such topics as the use of social media and electronic technologies, confidentiality, privacy, protection of employer information, intellectual property, and contact with the media and government agencies.

My previous reports touched on some of these policies and rules, and they are the sole focus of this report, which discusses seven recent cases. In the first six cases, I have concluded that at least some of the provisions in the employers’ policies and rules are overbroad and thus unlawful under the National Labor Relations Act. In the last case, I have concluded that the entire social media policy, as revised, is lawful under the Act, and I have attached this complete policy. I hope that this report, with its specific examples of various employer policies and rules, will provide additional guidance in this area."

By many indications, first impressions of this latest NLRB report have not been especially favorable.
