Compressed Work Week

A compressed work week does not change this principle – the workweek is still 40 hours; it just runs over fewer days.

Compressed Work Week is an alternative work schedule in which an employee works the standard number of weekly hours over fewer than five days. The most common forms are 4/10 (four 10-hour days), 9/80 (eighty hours over nine days), and 3/12 (three 12-hour days). Also called: compressed workweek, alternative workweek, 4/10 schedule, 9/80 schedule.

The common compressed schedule formats

FLSA and overtime: what changes (and what doesn’t)

Under the federal Fair Labor Standards Act (FLSA), non-exempt employees are owed overtime pay (1.5x regular rate) for hours worked above 40 in a defined workweek. A compressed work week does not change this principle – the workweek is still 40 hours; it just runs over fewer days. A 4/10 employee working exactly 40 hours has no overtime liability.

The 9/80 special case

In a 9/80 schedule, the employee works 9 hours Monday through Thursday and 8 hours on Friday in Week 1 (44 hours), then 9 hours Monday through Thursday and 0 hours Friday in Week 2 (36 hours). To avoid FLSA overtime on the 44-hour Week 1, employers define the workweek to split the 8-hour Friday – 4 hours falls into Week 1, 4 hours into Week 2. Each workweek now totals exactly 40 hours; no overtime liability. This technique requires the workweek definition to be documented and applied consistently.

State daily overtime: the trap

Four US states require daily overtime regardless of the weekly total:

California is the most procedurally specific: to operate a compressed workweek without daily overtime, the employer must conduct a secret-ballot election among affected non-exempt employees, achieve a two-thirds majority approval, and report the result to the Department of Industrial Relations per California DIR alternative workweek rules.

Pros and cons of a compressed work week

Benefits:

• Employee retention and engagement. Three-day weekends are routinely cited as the top retention factor in benefits surveys. Reduced churn pays back quickly.
• Reduced commuting cost and time. 20% fewer commute days; meaningful for hourly workers.
• Improved focus. Industry research (Iceland trials per Autonomy, Microsoft Japan 4-day pilot) shows productivity maintained or improved on compressed schedules.
• Recruiting differentiator. Compressed schedules show up in Glassdoor reviews and accelerate offer-acceptance in talent-tight markets.

Drawbacks:

• Fatigue and burnout risk. 10- and 12-hour days are harder than 8-hour days. Error rates and injury rates rise in safety-sensitive work over time.
• Coverage gaps. If half the team is off Fridays, customer-facing functions need staggered scheduling.
• State compliance overhead. California’s election procedure and other state daily overtime rules add real administrative cost.
• Childcare conflicts. 10-hour days conflict with school schedules and standard childcare windows for many employees.

How to implement a compressed work week

1. Define the business case. Retention pressure, recruiting signals, or productivity hypothesis. Without a defined goal, you cannot measure success.

1. Choose the schedule format. 4/10 for simplicity; 9/80 for industries where 4-day coverage gaps are not acceptable; 3/12 for clinical operations.
2. Run a 90-day pilot. Pilot one team or function. Measure pre-pilot baseline on engagement, output, customer SLAs, error rates, and absenteeism.
3. Handle state compliance. In California, run the alternative-workweek election before any non-exempt employee starts the new schedule.
4. Write the policy. Eligibility, schedule options, opt-in/opt-out process, coverage rules, manager discretion, and FLSA acknowledgement. This complements your existing time in lieu and floating holiday policies.
5. Train managers. Managers need to set expectations on availability, output measurement, and customer coverage.
6. Measure quarterly. Engagement, retention, productivity proxy, customer SLA, error rate. Most compressed schedules that fail do so because no one tracked them.

Sample compressed work week policy clauses

Eligibility: This policy applies to employees whose role functions can be performed on a compressed schedule without measurable degradation of service to customers, teammates, or business needs, subject to manager approval.

Available schedules: Employees may request one of the following: (a) 4/10 – four 10-hour days, with the same day off each week; (b) 9/80 – alternating Friday off across a two-week pay period.

Coverage requirement: No more than 50% of any team may take the same day off. Manager will assign or rotate off-days to maintain coverage.

Overtime: Non-exempt employees are paid overtime at 1.5x their regular rate for hours worked above 40 in the defined workweek. In California, Colorado, Nevada, and Alaska, additional state daily overtime rules apply.

Reversion: The company may revert affected employees to a standard 5/8 schedule with 30 days’ written notice if business need requires.

Per SHRM compressed workweek guidance, always have legal review the policy before rollout in states with daily overtime requirements.
