Eighty years ago, Congress formalized a 40 hour work week in the United States. That policy hasn’t changed since then, even though today’s workforce looks very different than it did in the 1940s. With so many people working from home these days or dropping out of the workforce altogether, is it time we rethink our employment laws? What if we worked four days a week instead of five? Would it completely upend our work culture? This week on Downside Up, Chris Cillizza is joined by Anne Helen Petersen, author of “Out of Office;” Angela Garbes, author of “Essential Labor;” and Charlotte Lockhart, founder of the nonprofit 4 Day Week - Global, to explore what the world would look if everyone works fewer hours.
