As political leaders appeared to be working toward finalizing a fiscal cliff deal, one of the country's top labor leaders said Monday night that he believes the proposal as outlined represents a raw deal for Democrats.

"Its not a good #fiscalcliff deal if it gives more tax cuts to 2 percent and sets the stage for more hostage taking," AFL-CIO President Richard Trumka said via Twitter while talks between Vice President Biden and Senate Minority Leader Mitch McConnell (R-Ky.) were still underway.

"Rs #fiscalcliff doublethink: fiscal crisis demands cuts in services, no investment in jobs but allows more tax cuts for richest Americans. We cant set the stage for further destabilizing hostage taking from Rs in the form of another debt ceiling crisis & another sequester crisis," he added in two subsequent tweets.

The Huffington Post's Sam Stein reports that Trumka backs a "fallback option" that would include an extension of the Bush-era tax rates on income below $200,000 for individuals and $250,000 for couples; the extension of unemployment insurance for the estimated 2 million Americans whose benefits are set to expire; and a "pledge" to work toward a deal on avoiding $110 billion in across-the-board federal budget cuts over the next few weeks.
