President-elect Donald Trump has nominated Andy Puzder, the CEO of the Hardee’s and Carl’s Jr. burger chains, to be America’s next labor secretary. In doing so, Trump may be drawing more attention to the plight of low-wage workers than he could have imagined. Puzder’s company violated minimum wage law by paying Hardee’s workers with pre-paid Visa debit cards. Workers incurred fees on those cards whenever they used ATMs outside of the designated network to redeem their pay. The workers’ pay rates were so low that the fees pushed their pay below the federal minimum wage of $7.25 per hour.
