After an aluminum manufacturing firm fired a worker for writing a profanity on a company sign-up sheet, the employee pursued their wrongful firing in court- and won. The D.C. NLRB found that the firing was unlawful, and that the employee was protected under federal labor law. Now, the firm will be taking the court to the D.C. Circuit to receive another opinion. The firm’s lawyers will be arguing that the firm had the right to fire the employee on the grounds of vandalizing company property, and making a comment that may have harmed other workers.
