Here’s the opening of a letter sent to Nancy Pelosi and Harry Reid:

When you and the President sought our support for the Affordable Care Act (ACA), you pledged that if we liked the health plans we have now, we could keep them. Sadly, that promise is under threat. Right now, unless you and the Obama Administration enact an equitable fix, the ACA will shatter not only our hard-earned health benefits, but destroy the foundation of the 40 hour work week that is the backbone of the American middle class.

Like millions of other Americans, our members are front-line workers in the American economy. We have been strong supporters of the notion that all Americans should have access to quality, affordable health care. We have also been strong supporters of you. In campaign after campaign we have put boots on the ground, gone door-to-door to get out the vote, run phone banks and raised money to secure this vision.

Now this vision has come back to haunt us.

The letter is from the head of the Teamsters and two other unions. Read the whole thing.
