In contract bargaining with IBEW Local 48, KGW-TV is proposing to end exclusive union jurisdiction — and let others do the work of union camera operators and technicians. Managers say they’re proposing that in order to better compete with companies like Google and Amazon. But when Local 48 asked for detailed information that would justify such a proposal, parent company Gannett (now Tegna) refused. The National Labor Relations Board thinks that refusal violated the law’s requirement to bargain in good faith. A federal judge will decide the matter based on arguments from the two sides in a three-day hearing that took place March 8-10.
