Negotiators for the state and the two unions did return to the bargaining table today in an effort to avoid a strike next week. The talks were originally set for two weeks ago, but both sides agreed to put them on hold in the immediate aftermath of the East Coast attacks. Though workers say they're still set to strike Monday morning, walking off the job now raises a different set of implications than it did before September 11th. Mario Bognanno (BOHN-yah-noh) is a professor of Industrial Relations at the Carlson School of Management. He has studied the frequency and duration of strikes during two other national crises-- World War II and the Korean War. We asked him for some historical perspective.
