A company included the following in its employee ("partner") handbook: "We honor confidentiality. We recognize and protect the confidentiality of any information concerning the company, its business plans, its partners [employees], new business efforts, customers, accounting and financial matters." A union at- tempting to organize the company's workers challenges the policy. Does the policy violate the NLRA? (Cintas Corporation v. NLRB, 482 F.3d 463 (D.C. 2007))
