Some employees of Cablevision in Brooklyn, members of the Communication Workers of America union, were at a company BBQ circulating a petition to decertify their local, 1109.  Naturally the local’s officials objected, and they threatened the petition circulators.

I just want you to understand, to be perfectly clear that CWA we’re probably going to personally sue y’all[.]

It’s especially serious when an NLRB administrative judge objects to the union local’s behavior, ruling these union officials had violated Federal labor law with their threats.  It’ll be interesting to see how the NLRB board itself rules on the union’s inevitable appeal.
