In United Parcel Serv. v. NLRB, 41 F.3d 1068 (6th Cir. 1994), we held that the employer's refusal to allow employees to wear union pins, while allowing the wearing of other pins, did not constitute discrimination in violation of Section(s) 8(a)(1).
In NLRB v. Harrah's Club, 337 F.2d 177 (9th Cir. 1964) (Harrah's Club), we reviewed a National Labor Relations Board (Board) order that concluded that section 7 of the NLRA, 29 U.S.C. § 158(a)(1), granted a casino's public contact uniformed employees a right to wear union buttons or pins, even though the wearing of the union buttons was not part of any concerted campaign to organize the employees, promote collective bargaining, or gain better working conditions.
