Office of Management and Budget Director Mick Mulvaney (Credit: Getty/Win McNamee) In a move that threatens to take hundreds of millions of dollars from American workers who rely on tips to make a living, Office of Management and Budget (OMB) Director Mick Mulvaney sided with Labor Secretary Alexander Acosta and overruled the White House regulatory affairs chief by releasing a contentious rule about tip-pooling and knowingly withholding accurate data. The rule, which has been pushed by the Department of Labor in recent months, would legally allow employers to profit off workers’ tips — collectively pocketing an estimated $640 million more for employers — so long as the workers are at least paid the federal minimum wage.
