Cooling-off Period
Under the Railway Labor Act (RLA), a period when parties that are at a collective bargaining impasse are prohibited from engaging in self help. In particular, when a National Mediation Board (NMB) mediator cannot break the impasse and the parties cannot agree to participate in interest arbitration, the NMB starts a 30-day cooling-off period by notifying the parties in writing that mediation has failed.
