Illegal Strike Law and Legal Definition

Illegal Strike is a strike that is called in violation of law. An illegal strike ignores cooling-off period restrictions or an absolute statutory ban. Such strike is entered without regard to the no-strike agreement of the union. The 2005 New York City transit strike called by the Transport Workers Union Local 100 (TWU) is an example for illegal strike. TWU’s President, Roger Toussaint was sentenced to ten days in jail and the union was fined 2.5 million dollars by the court for the illegal strike and damages caused.
