29 CFR 101.2: Initiation of unfair labor practice cases.

The investigation of an alleged violation of the National Labor Relations Act is initiated by the filing of a charge, which must be in writing and signed, and must either be notarized or must contain a declaration by the person signing it, under the penalties of the Criminal Code, that its contents are true and correct to the best of the persons' knowledge and belief. The charge is filed with the Regional Director for the Region in which the alleged violations have occurred or are occurring. A blank form for filing such charge is supplied by the Regional Office upon request. The charge contains the name and address of the person against whom the charge is made and a statement of the facts constituting the alleged unfair labor practices.
