Bernie Sanders wants the US to adopt a 32-hour workweek. Could workers and companies benefit?

The 40-hour workweek has been standard in the U.S. for more than eight decades. Now some members of Congress want to give hourly workers an extra day off.

Sen. Bernie Sanders, the far-left independent from Vermont, this week introduced a bill that would shorten to 32 hours the amount of time many Americans can work each week before they're owed overtime.

Given advances in automation, robotics and artificial intelligence, Sanders says U.S. companies can afford to give employees more time off without cutting their pay and benefits.

Critics say a mandated shorter week would force many companies to hire additional workers or lose productivity.
