WASHINGTON (AP) — The National Labor Relations Board ruled against the CNN cable television network on Monday in an 11-year-old labor dispute, ordering the network to rehire or compensate about 300 former workers.

The NLRB agreed with a November 2008 ruling by one of its administrative judges that CNN improperly replaced a unionized subcontractor, Team Video Services (TVS), with in-house non-union staffers, claiming “anti-union” bias.
