The NLRB issued an official complaint against the Hyatt Regency Chicago earlier this week, concerning the Hotel’s possible tracking of guests and employees using facial recognition software. The initial complaint was submitted by UNITE HERE Local 1 in September, which represents about 800 employees at the Hyatt Regency. According to state law, it is illegal for companies to gather biometric data without first getting consent. The union is alleging that this is a failure to bargain in good faith, but Hyatt denied that they were breaking any laws.
