Your love of the 4-day workweek would exclude half the American workforce

Along with better work-life balance to prevent burnout, shorter workweeks might increase productivity.

Microsoft, for instance, found that reducing the workweek by one day led to a 40% boost in productivity. A buzzy Wall Street Journal article last month highlighted how employees at a German company got the same amount of work done after cutting three hours in a workday.

Yet the reality for low-wage workers is that they are already being worked to optimal productivity. Scheduling algorithms, such as Kronos, use AI to devise worker shifts around when to best meet a store's demand. Companies increased use in these scheduling algorithms in the past decade, according to Adrian Haro, CEO of The Workers Lab.

The issue, however, with scheduling technology is that it gives little forewarning to hourly workers on what their daily schedules will look like. As many as 60% of hourly workers get less than two weeks' notice of changes to their schedule, according to the University of California at Berkeley's Shift Project.

Schneider, a researcher at the Shift Project, says hourly employees want to work more hours outside of just what these algorithms decide for them.

"The problem is, we do see people working a less-than-40-hour week, but they don't like it. They want more hours because they're paid hourly and not very much," Schneider told Business Insider. "For these workers, there's a clear time-money trade-off."

Leyba said that, as with teachers, nurses are often overworked. A recent report as many as half of nurses and doctors suffer from burnout.

Yet the burnout stems not from time on the job but the quality of work.

Many nurse advocates say working with too many patients is the root of the issue, and groups like Nurses Take DC and SEIU121RN have lobbied for safer nurse-to-patient staffing ratios. So far, only California caps the number of patients a nurse can have at once, despite research that suggests fewer patients lead to higher-quality patient care.

Similarly, the National Union of Teachers found teachers with larger class sizes work the longest hours. Many teachers have gone on strike over the last few years, most recently in Chicago, protesting increasing class sizes and dwindling pay.

In the case of low-wage, hourly workers, a bill to give people better notice of schedules just got reintroduced into Congress by presidential candidate Elizabeth Warren on Tuesday.

While most experts agree a discussion around shorter workweeks is a good start, as it suggests — but Kashen says non-white-collar workers must be at the center of this discussion.

"White-collar workers are able to have a different conversation because they have more agency in the workplace, and they also have more resources and higher wages," Kashen says. "If we can improve working conditions for the most vulnerable then that will really help everyone."
