As big labor unions have slowly but surely found out more about ObamaCare and precisely “what’s in it,” they’ve become increasingly dismayed about the whole thing and the effect it’s going to have on their workers. After first actively working toward the law’s passage and then helping to encourage the president’s reelection, unions have started figuring out that the law endangers the union-sponsored health care plans that are often used in industries where contracts and hours fluctuate — which is rather inconvenient, because the attractive health care option are usually one of the biggest reasons for joining a union in the fist place.

More and more unions have been getting vocal with their complaints, and back in January, I queried, “Who wants to put money on the Obama administration finding a way to make the unions happy here?”

Ahem. They’re certainly trying, via the WSJ:

Unions are making some progress in getting the Obama administration to address their concerns about the new health law, and Labor Secretary Tom Perez is playing a central role, AFL-CIO President Richard Trumka said Thursday.

“We’ve been working with the administration to find solutions to what I think are inadvertent holes in the act. I’m hopeful that we’ll get something done in the very near future,” Mr. Trumka said at a breakfast with reporters sponsored by the Christian Science Monitor. …

Mr. Perez, who has been labor secretary since July, is “in the middle” of organized labor’s continuing talks with the Obama administration over costs and other concerns about the health law, Mr. Trumka said, adding that he has met with Mr. Perez and White House officials as recently as Tuesday. …

The Labor Department didn’t immediately respond to a request for comment Thursday, and Mr. Trumka said he had no specifics to share from the talks, which he said are “a moving target.”

Business as usual.
