The US Court of Appeals upheld a NLRB ruling that Quicken Loans Inc. had obstructed employees' ability to discuss working conditions thru various company policies. Quicken employed a confidentiality rule which restricted workers from sharing personnel information, as well as a non-disparagement rule prohibiting employees from speaking out against company policies or management. Quicken had appealed the NLRB decision on grounds that there was no proof that the policies had resulted in disciplinary action or that employees had actually been intimidated. Upon review, however, the court ruled Quicken's policies were unlawful even without enforcement, as employees could objectionably view the policies as "limits on their freedom".
