The General Counsel of the NLRB is responsible for investigating unfair labor practice charges and making the decision whether to issue a complaint. This job is delegated to the Regional Director of the region of the NLRB in which the charge has been filed; the Regional Director in turn assigns it to an employee of the region. It is the responsibility of the charging party to identify the witnesses who can support its charge; should it fail to do so the Regional Director will typically dismiss the charge.
