This study examines the difficult choice faced by members of a striking bargaining unit between withholding labor or crossing the picket line in violation of the prevailing behavioral norm. Using duration analysis, we test a model of crossing behavior using data on individual football players during the 1987 National Football League strike. A notable finding is that nonwhite players are less willing to cross the picket line if their team union representative is also nonwhite. Willingness to cross the line is also influenced by teammate crossing and proxies for expected career length, demand for current income, and expected benefits from union demands.

We hypothesize that past strike experience will have a negative or "teetotaler" effect on a collective bargaining unit's propensity to strike in future negotiations, other things being equal. We test this using a unique micro-level sample comprising four consecutive negotiations by 147 bargaining units in U.S. manufacturing industries, controlling for observable and unobservable differences among bargaining pairs in the propensity to strike. Our results are consistent with the view that the experience of striking is, indeed, sobering: lagged strike experience variables have a significantly negative effect on the propensity to strike in the current negotiation.
