Scabby the Rat is a giant inflatable rodent that is displayed outside of firm offices in New York City during union labor disputes. The rat is used as a symbol of organized labor and union protests. However, many fear that Scabby the Rat may soon be banned due to a number of cases where the NLRB has determined that inflatable balloons are unlawful. The NLRB has taken the position that the use of inflatable balloons constitutes a form of disruptive, illegal picketing.
