In a rare NLRB ruling that perhaps we can all support, the Board held that an employer committed an unfair labor practice by pushing a union business agent down the stairs of a construction trailer, causing him to hit his hand and neck on a railing. The employer had a "no solicitation" sign on the trailer, and the union representatives came without an appointment to ask about subcontractors working on a construction project. The project superintendent said that he was tired of interruptions and told the two to leave. So far, so good, but then he pushed the business agent down the stairs. The employer contended that its property interest justified "excluding" the union representatives from the premises. The Board disagreed, finding that the business agent was assaulted and that the employer was liable for his back pay and medical expenses.
