When it comes to intimidation in the pursuit of economic interest, organized labor long has been a master of the art. Such behavior is especially noxious and costly among construction unions. This past Monday through Wednesday, February 11-13, National Review Online published three articles under the title "Goon City" - here, here and here - on how Philadelphia's construction unions are imposing their brand of justice on open-shop contractors, workers and project sites. Assault, threats, harassment, vandalism, and arson are simply ways of doing business. Union bosses and their lawyers rationalize this behavior. Victims usually don't publicly complain about it. And the city council has every incentive to wink at it. The three-part series brings home with force the reality that union violence, in Philadelphia and elsewhere, is hardly "a thing of the past."
