1. How the 9/80 Compressed Work Schedule Operates

The 9/80 work schedule is one of the most popular compressed work arrangements among aerospace, defense, engineering, and federal government employers. Over a 14-day pay period, employees fulfill their required 80 work hours across nine working days rather than the traditional ten.

The schedule breaks down into two distinct workweeks:

Week 1: The Working Week (44 Hours)

Monday – Thursday: 9 hours worked each day (36 hours)
Friday: 8 hours worked (44 total clock hours)
Saturday – Sunday: Standard weekend rest

Week 2: The Flex Week (36 Hours)

Monday – Thursday: 9 hours worked each day (36 hours)
Friday (Flex Day Off): 0 hours worked (3-Day Weekend!)
Saturday – Sunday: Standard weekend rest

2. The Legal "Friday Midday Split" Under FLSA

A common question is: If an employee works 44 hours in Week 1, doesn't that require 4 hours of statutory overtime pay?

Under the US Fair Labor Standards Act (29 U.S.C. § 207), overtime is strictly assessed over a designated 168-hour workweek. To make 9/80 fully compliant without paying involuntary overtime, employers officially define the statutory workweek to start and end midway through Friday's shift (usually 12:00 PM or 12:30 PM, exactly four hours into the 8-hour workday).

The FLSA Accounting Breakdown:

Statutory Workweek 1: Mon-Thu (36 hrs) + Fri Morning (4 hrs) = 40.0 Hours.

Statutory Workweek 2: Fri Afternoon (4 hrs) + Mon-Thu (36 hrs) + Off Fri (0 hrs) = 40.0 Hours.

Because neither statutory workweek exceeds 40.0 hours, no overtime liability is generated for non-exempt employees.

3. 9/80 vs. 4/10 vs. Standard 5/40 Schedule

Schedule	Shift Length	Days Off / Year	Fatigue Risk	Primary Advantage
9/80 Compressed	9 hrs (one 8h day)	130 days	Low to Moderate	26 extra 3-day weekends with manageable 9h days
4/10 Schedule	10 hrs daily	156 days	Moderate to High	Every Friday off, saving 52 commute days/yr
Traditional 5/40	8 hrs daily	104 days	Lowest	Predictable evening routine, universal business alignment

Frequently asked questions

What is a 9/80 work schedule and how does it work?

A 9/80 work schedule is a compressed work arrangement spanning a two-week (14-day) payroll period. Employees work eighty hours over nine business days instead of the standard ten, earning every other Friday (or Monday) off. The standard breakdown consists of eight 9-hour days, one 8-hour day, and one scheduled flex day off.

How is the FLSA statutory workweek defined for 9/80 to avoid overtime?

Under the US Fair Labor Standards Act (FLSA), non-exempt employees must be paid overtime for any hours worked over 40 in a single 168-hour statutory workweek. To avoid triggering 4 hours of weekly overtime, employers define the statutory workweek to begin and end exactly midway through the 8-hour working Friday (e.g., Friday at 12:00 PM). Four hours of that Friday count toward Week 1 (4 x 9h + 4h = 40 hours), and the remaining four hours count toward Week 2 (4h + 4 x 9h = 40 hours).

How many three-day weekends do employees get on a 9/80 schedule?

Employees on a standard Friday-off 9/80 schedule receive 26 three-day weekends every year. This equates to 26 additional non-working weekdays annually without sacrificing total full-time salary or standard 80-hour biweekly pay.

How are paid holidays handled on a 9/80 schedule?

Most corporate and government holiday policies grant 8 hours of holiday pay. If a federal holiday falls on a 9-hour workday, employees typically either apply 1 hour of accrued PTO, work an extra hour during that pay period, or rely on employer flex policies. If a holiday falls on an employee's scheduled flex day off, employers usually designate an alternate holiday (an 'in-lieu-of' day on Thursday or Monday).

What is the difference between a 9/80 and a 4/10 schedule?

On a 4/10 schedule, employees work four 10-hour days every single week, earning every Friday off. While attractive, 10-hour shifts can lead to fatigue. The 9/80 schedule offers a gentler compromise: daily shifts are only 9 hours, and employees receive every other Friday off while keeping standard 40-hour weekly FLSA accounting intact.

Can I export my 9/80 schedule to Google Calendar or Outlook?

Yes. Select your cycle start date, verify that your working and off Fridays match your company's schedule cohort (Squad A vs Squad B), and click 'Download ICS' to import the full schedule into Google Calendar, Outlook, or Apple Calendar.
