The NLRB reopened from shutdown status on November 13, 2025. Due dates to file or serve most documents were tolled during the period of the shutdown, although due dates cannot be tolled for filing and service of unfair labor practice charges, applications for awards of fees and other expenses under the Equal Access to Justice Act, and certain representation petitions. For documents where tolling applies, the terms are that for each day on which the Agency’s offices were closed for all or any portion of the day, one day is added to the time for filing or service of the document. If the new due date falls on a weekend or holiday, the new due date will be moved to the next business day. For example, if the original due date was October 7, 2025 and the shutdown lasted 43 days, the revised due date is November 19, 2025. See chart for revised due dates.
