“Fuyao Glass America Inc. won’t be prosecuted for alleged labor violations depicted in a recent Academy Award-winning documentary film because the accusations were made too late, a federal labor board official decided. Federal law typically allows workers and others to file unfair labor practice charges with the National Labor Relations Board within six months after “clear and unequivocal notice” of a violation. The clock started ticking for Fuyao workers when “American Factory” premiered at the Sundance Film Festival in January 2019, a board official said Monday.”
