An NLRB judge ruled in favor of Giant Eagle employees who filed a complaint against the company for urging workers to get their union, United Food and Commercial Workers Local 23, to sign waivers allowing them to release information about upcoming wage and benefit information before the representation election. These claims have been outlined in official NLRB documents that were released to the press. In a separate issue, Giant Eagle announced it would not consider openly pro-union employees for promotion opportunities unless the union supplied a waiver promising not to file complaints with the labor board if they offered that employee a promotion.
