Media coverage of the Employee Free Choice Act has so far focused mostly on the provision allowing workers to choose whether to hold a union election by secret ballot -- the only option now available under law -- or by simply signing union cards. But that's not the only change EFCA would make to U.S. labor law: It would also provide for mandatory injunctions against companies for unfair labor practices during union election campaigns.

Just how common are such practices? That was the topic of the index in this week's edition of the Facing South e-newsletter, which also includes a roundup of news from across the South and special features.
