An illegal strike is a work stoppage or strike action that violates the law. Most public-sector strikes are illegal, along with those that violate an existing labor contract, are not properly authorized by union membership, or contravene a court order.
The Taft-Hartley Act, formally known as the Labor-Management Relations Act of 1947, aims to protect employers' rights to resist unionization and restrict union activities, imposing on unions many of the conditions for good faith bargaining previously imposed on management by earlier laws.
