Compressed Workweek

A schedule that fits standard weekly work hours into fewer than five days — most commonly four 10-hour days.

A compressed workweek is a schedule arrangement in which an employee works their standard total weekly hours in fewer than the typical five days. The most common version is 4/10: four days of ten hours each, for a total of 40 hours, with one weekday (often Friday or Monday) off each week. Another variant is the 9/80 schedule: employees work 80 hours over nine days in a two-week period (eight nine-hour days and one eight-hour day), resulting in one full day off every two weeks. A third variant, sometimes confused with the compressed workweek, is the four-day, 32-hour workweek — which actually reduces total hours worked, not just the number of days.

Compressed workweeks are distinct from flexible schedules (which may allow variable start/end times but maintain five-day weeks) and remote work (which changes location but not necessarily schedule structure). They are most common in industries where longer shifts are operationally practical: manufacturing, utilities, healthcare, law enforcement, and government agencies. In professional and knowledge-worker contexts, compressed workweeks have gained popularity as a recruitment and retention tool, though manager adoption varies widely — some organizations offer them in policy but create cultural pressure that discourages actual use.

For employees, the 4/10 schedule's main appeal is a three-day weekend every week — a significant quality-of-life benefit that correlates with reduced commuting cost (one fewer commute per week), lower childcare costs on the day off, and increased time for personal obligations. The main drawback is longer daily hours (10 vs. 8), which can increase fatigue for roles requiring sustained concentration. Overtime rules also require attention: hourly workers are typically owed overtime for hours over 8 in a day in California regardless of the weekly total, which can make 4/10 schedules more expensive for employers in that state.

Compressed Workweek vs. Four-Day Workweek vs. Flex Schedule

  • Compressed (4/10): same 40 hours, 4 days instead of 5. Full pay, longer daily hours, one day off per week.
  • Four-day 32-hour week: reduced total hours (32 vs. 40) with same or similar pay — a true reduction in workload, not just schedule compression.
  • 9/80: 80 hours over 9 days in a 2-week cycle — one day off every two weeks.
  • Flex schedule: variable start/end times within a 5-day week (arrive 7am–9am, leave 3pm–5pm).
  • Remote work: changes location, not necessarily schedule structure — can be combined with any of the above.

How to Propose One

If your company doesn't formally offer compressed workweeks, you can often negotiate one informally. Frame it around business outcomes rather than personal preference: 'I'd like to try a 4/10 schedule for 90 days and will be fully available Monday–Thursday. I'll track my output and we can evaluate at the end of the trial.' Offer to be reachable on your day off for genuine emergencies (defined specifically — not just any question that comes up). A 90-day trial with a defined evaluation point lowers the perceived risk for a skeptical manager and creates a built-in checkpoint for both sides.

Example

A city utility department switches its field crews from 5/8 schedules to 4/10 schedules. Total hours worked per week remain 40, but each crew now has Fridays off. Crew absenteeism drops 18% in the first year — most planned personal appointments (doctor, school events) now happen on Fridays rather than eating into scheduled workdays. Overtime usage drops because longer shifts make it easier to complete field work within the allotted time. Two crew members request to return to 5/8 after six months because 10-hour physical shifts are too tiring — the utility accommodates them. The remaining crews keep the 4/10 arrangement and it becomes a recruiting advantage for the utility in a tight labor market.
