Oh dear. There goes Obama, ruining the Republicans' fun for them:

President Barack Obama would veto the House GOP's bill to repeal the Obamacare provision that defines the work week as 30 hours, the White House said Wednesday in a formal statement.The House is expected to vote Wednesday on the bill that would increase the work week definition from 30 hours to 40 hours under Obamacare. The White House said that the bill would "increase the deficit, reduce the number of Americans with employer-based health insurance coverage, and create incentives for employers to shift their employees to part-time work -- causing the problem it intends to solve."

As TPM previously reported, the GOP's plan to redefine the work week as 40 hours would strip an estimated 1 million workers of employer-sponsored health insurance and increase the deficit by $74 billion over 10 years, according to the Congressional Budget Office and Joint Committee on Taxation.
