June 23 (Reuters) – A U.S. appeals court on Monday agreed with the National Labor Relations Board that a Pennsylvania factory worker’s critical comments about the plant remaining open in the early days of the COVID-19 pandemic were protected by federal labor law.
A unanimous three-judge panel of the Philadelphia-based 3rd U.S. Circuit Court of Appeals rejected claims by Miller Plastic Products that the worker, Ronald Vincer, was not acting for the benefit of other employees when he made the comments at a 2020 meeting.
