(Providence, RI) -- United Nurses and Allied Professionals Local 5098 and Rhode Island Hospital are filing complaints against each other with the National Labor Relations Board. The complaints were filed Thursday, just one day after the two sides met for contract talks for the first time since the nurses went on strike. Rhode Island Hospital alleges the nurses' union has negotiated in bad faith, while the union said the hospital has made changes to workplace conditions that are supposed to be subjected to collective bargaining. A federal mediator scheduled a second round of negotiations for next Wednesday.
