"NLRB judge: Employees can bitch about their jobs on Facebook"

Thus writes Alison Frankel. Here's the decision. Not sure how that applies to blogs! There's a "concerted effort" element that Facebook lends itself to:

In Myers Industries (Myers I), 268 NLRB 493 (1984), and in Myers Industries (Myers II) 281 NLRB 882 (1986), the Board held that "concerted activities" protected by Section 7 are those "engaged in with or on the authority of other employees, and not solely by and on behalf of the employee himself." However, the activities of a single employee in enlisting the support
of fellow employees in mutual aid and protection is as much concerted activity as is ordinary group activity.
