In Battle's Transportation Inc., the National Labor Relations Board (NLRB) found that an employer violated Section 8(a)(1) of the National Labor Relations Act (NLRA) by having employees sign an overbroad confidentiality agreement and by issuing a memo to employees instructing them not to discuss company business with customers. The NLRB also found that the employer unlawfully demanded that the union replace its steward and suspended and discharged the steward for engaging in protected union activity.
