If, after the strike, any carrier increases its frequency or gauge on the routes that the striking carrier operated, then it is considered struck work. That is why MECs set up strike centers with a call bank. The call bank is used so pilots from other carriers can call in and see if the flight they are operating is struck work. At PCL we were given a number just prior to the Mesaba strike, if you remember, and we were supposed to call in to see if a flight we were operating was on our schedule prior to the cutoff date. If it wasn't, you were supposed to refuse it on the basis of struck work. Mesaba never got to a strike, but the system was in place, and all MECs were notified of the struck work policy well in advance.
