Before this thread gets too stale, I did find a legal paper from Duke, 2006, talking about how certain kinds of blogging are likely protected by NLRA, "When is employee blogging protected by section 7 of the NLRA?"

I wish I could find the older case about the leaflets. IIRC it was from the late 1970s.
