Bloomberg News today runs a report "‘Stay Union-Free’ Pushed by Target, Michaels as Obama Law Looms."  There is no real new information in the piece, but the following passages refer to the current approach of the retailers mentioned in the headline:

“If proposed labor relations legislation is adopted, allowing third-party involvement or interruptions to our business, our business could be impacted,” Michaels Stores of Irving, Texas, the world’s largest arts-and-crafts retailer, said in its earnings filing this month.

As long noted, once the debate over healthcare legislation is completed, the Congress is expected to take up EFCA once again.
