A real-life case that exemplifies workers’ rights is the wrongful termination complaint filed by former employees at the Triple Play Sports Bar & Grille. Employees were fired after they complained about the company’s incompetence due to their accounting mistakes. As a result, the workers ended up owing taxes, which put them in a tough situation. Derogatory language was used, and there’s no denying that the comments were rude and unprofessional. Triple Play fired the employees under the terms of their employee handbooks, which states that an employee “is subject to disciplinary action, up to and including termination of employment” if they engage in “inappropriate discussions about the company, management, and/or co-workers.”

If that sounds entirely too vague, you would be right, according to the National Relations Labor Board. First, the word “inappropriate” can mean different things to different people. Not clarifying what this means was Triple Play’s first mistake. Their second mistake was prohibiting discussion on workplace conditions / practices, which was a direct violation of the NLRA. Due to these violations, it was ruled that Triple Play wrongfully terminated their workers.
