Democratic Sen. Joe Manchin (W.Va.) wants to kill a new progressive labor reform, and hes teaming up with Republicans to try to do it.

Last week, the agency that enforces collective-bargaining law rolled out its new rule on joint employers. The regulation makes it more likely that big companies like McDonalds will be held responsible for unfair labor practices involving their franchisees or subcontractors, or even forced to bargain with a workers union.

While labor groups have hailed the change as commonsense and long overdue, Manchin has panned it as government overreach and vowed to stop it from going into effect.

The West Virginia senator says he plans to join Republican Sen. Bill Cassidy (La.), ranking member of the Senates labor committee, on a legislative maneuver that would overturn the National Labor Relations Boards joint employer rule and possibly make it harder to implement a similar rule in the future.

Manchin told HuffPost he is deeply opposed to the rule.

It basically just destroys the entrepreneurial spirit, the capitalist spirit, everything that we are as Americans, he said on Capitol Hill Tuesday.

Cassidy claimed in a statement that the reform would unfairly saddle big franchisors with liabilities that belong to their thousands of smaller franchisees.

The NLRB, an independent agency led by Senate-confirmed White House appointees, declined to comment on the remarks from Manchin and Cassidy.

For years, big corporations like fast-food chains have denied liability for labor law violations inside the workplaces that produce or sell their products. They claim those responsibilities should lie with the smaller firms they contract with, like the fast-food franchisees who generally run the stores and sign workers paychecks.

But worker advocates say the companies at the top of the chain exert all kinds of control over working conditions and therefore should be held accountable when laws are broken.

Trade groups have pushed back hard against this legal reading with the help of mostly Republican lawmakers.

Now under Democratic control, the NLRB has moved forward with a joint employment rule that would effectively wipe out a McDonalds-friendly version that was instituted by a GOP board under former President Donald Trump . The new rule would make it more likely that big corporations get pulled into legal proceedings as joint employers when workers are threatened or retaliated against for trying to organize.
