Upon filing of unfair labor practice charges, the Board will seek an informal response from the employer or union against whom the charge was filed. Board staff then may meet with the parties to investigate the charge and explore the informal resolution of it. In some cases, the Board will not conduct an investigation beyond the pleadings, and will decide whether to issue a complaint based on the pleadings. If a complaint is issued, an evidentiary hearing governed by the Rules of Evidence is conducted by a three member panel of the Board. After providing the parties with an opportunity to file briefs, the Board issues a written decision.
