What Is a 9/80 Work Schedule?

A 9/80 work schedule is a compressed schedule where employees work 80 hours across 9 days instead of 10, earning every other Friday off: eight 9-hour days, one 8-hour day, and one scheduled day off per two-week period. It's common in engineering, aerospace, government, and manufacturing - and increasingly a recruiting lever, because a guaranteed 26 three-day weekends a year is a benefit candidates can feel immediately.

How the 9/80 schedule works mechanically

  • Week 1: four 9-hour days (Mon-Thu) + 8 hours Friday = 44 hours.
  • Week 2: four 9-hour days (Mon-Thu) + Friday off = 36 hours. Total: 80 hours / 9 days.
  • Payroll splits the 8-hour Friday at midday so each workweek stays at 40 hours - the detail that keeps non-exempt employees out of unintended overtime (US FLSA).
  • Teams usually stagger A/B groups so the office is never empty on Fridays.

Pros, cons, and who it fits

  • Pros: 26 extra full days off per year, fewer commutes, longer uninterrupted focus blocks, real recruiting differentiation.
  • Cons: 9-hour days strain caregivers, coverage roles need A/B scheduling, and meetings compress into fewer shared hours.
  • Fits: engineering, government, manufacturing, agencies. Poor fit: customer-facing coverage roles without staggering.
  • Hiring angle: if you offer 9/80, put it in the job description and interviews - schedule flexibility consistently ranks among top decision factors for candidates.

Frequently Asked Questions

Is a 9/80 schedule the same as a 4/10 schedule?

No. A 4/10 works 40 hours in four 10-hour days every week (every Friday off); a 9/80 works 80 hours over two weeks in nine days (every other Friday off). 4/10 gives more days off but longer days; 9/80 is the gentler compression.

How does overtime work on a 9/80 schedule?

In the US, employers define the workweek to split the 8-hour Friday at its midpoint, so each week totals exactly 40 hours and the schedule itself triggers no overtime for non-exempt staff. Hours beyond scheduled time still accrue overtime normally. Check state rules - California daily-overtime requires an alternative workweek election.
