Another report from Think Progress:
Sen. Mark Pryor (D-AR) told The Hill yesterday that "he intends to approach Sen. Arlen Specter (R-PA) on the Senate floor this week to see" if they can craft an alternative to the Employee Free Choice Act, which Specter effectively blocked last week. "I see this time now as really an opportunity for compromise or for a new approach on addressing some of the issues that revolve around that issue," said Pryor.
Specifics? Pryor offered none in the article linked. He said the process wasn't working for business or labor as now structured. Actually, I think it's working just fine for business. Which is to say not at all for workers.
