The traditional workweek was largely designed around a five-day, 40-hour schedule, but the way people work has changed significantly since that model became widespread.

At the same time, many industries still depend on fixed schedules, and shorter workweeks may create challenges for employers, customers, and workers in sectors where continuous coverage is essential. With trials of four-day workweeks producing mixed but often promising results, is the modern workweek still suited to the way people live and work today?
