The National Labor Relations Board and social media are the best of friends. “Over the past several years, it seems that the board will find almost any kind of employee speech—especially in social media—to be protected by the Act,” writes attorney Fiona Ong of Shawe Rosenthal, in this recent blog post.

But finally, the line has been crossed, she reports, in the case of Richmond District Neighborhood Center. In the case, two employees of an afterschool program discussed, via a public Facebook conversation, the unhappiness of their situation. Another employee took a screenshot and gave it to the employer, who didn’t rehire the aggrieved employees for the next year.
