The Four-Day Workweek: Feasibility Assessment for Employers

The four-day workweek has moved from radical concept to serious consideration for many employers. High-profile trials and growing employee demand have put the idea on leadership agendas across industries. Before committing to or dismissing the concept, employers should understand the different models, weigh the practical challenges, and consider a structured approach to evaluation.

Four-Day Workweek Models

The term "four-day workweek" encompasses several distinct approaches:

Compressed schedule (4 x 10)

Employees work four 10-hour days instead of five 8-hour days. Total weekly hours remain at 40.

• Advantages: No reduction in hours or pay. Relatively simple to implement. Employees gain a full day off.
• Challenges: Longer daily hours can increase fatigue and reduce productivity in the final hours. May conflict with state daily overtime laws (California, for example, requires overtime pay after 8 hours in a day). Childcare and school schedules may not align with 10-hour days.

Reduced hours (4 x 8)

Employees work four 8-hour days (32 hours total) at the same pay as a traditional 40-hour week.

• Advantages: Genuine reduction in work time. Strongest impact on employee satisfaction and work-life balance. Forces prioritization and efficiency improvements.
• Challenges: Requires maintaining output in fewer hours. Not viable for all roles or industries. Represents a real cost increase per hour of labor if productivity does not fully compensate.

Alternating schedules

Teams rotate so that the office is staffed five days per week, but each employee works only four days. Different employees have different days off.

• Advantages: Maintains five-day business operations and customer availability. Can reduce facility costs through hot-desking.
• Challenges: Coordination complexity. May reduce team overlap time. Some employees may receive less desirable days off.

Seasonal or periodic

A four-day week during slower business periods (summer, post-holiday), reverting to five days during peak times.

• Advantages: Provides the benefit without year-round commitment. Tests the model before permanent adoption.
• Challenges: Employees may resist returning to five days. Creates scheduling inconsistency.

Feasibility Considerations by Industry

The four-day workweek is not equally feasible across all industries:

Higher feasibility:

• Knowledge work and professional services (output-based rather than hours-based)
• Technology and software development
• Marketing, design, and creative agencies
• Corporate administrative functions

Moderate feasibility (with scheduling creativity):

• Healthcare (rotating schedules are already common)
• Manufacturing (shift-based operations can be restructured)
• Education (modified academic calendars exist)

Lower feasibility (without staffing changes):

• Retail and hospitality (customer-facing hours cannot easily be reduced)
• Emergency services and public safety
• Customer support operations with extended hours
• Roles requiring continuous coverage

For customer-facing operations, a four-day workweek typically requires either additional hiring to maintain coverage or client communication about modified availability.

Conducting a Pilot

Rather than committing to a permanent change, run a structured pilot:

Design

• Select one or two teams or departments for the pilot
• Define the model (compressed or reduced hours)
• Set a pilot duration (three to six months provides sufficient data)
• Establish measurable success criteria before the pilot begins

Metrics to track

• Productivity: Output volume and quality compared to the pre-pilot period
• Revenue: Impact on revenue-generating activities and client satisfaction
• Employee satisfaction: Survey employees before, during, and after the pilot
• Absenteeism: Unplanned absences often decrease when employees have more scheduled time off
• Retention: Monitor whether participating employees are less likely to leave
• Customer satisfaction: Track client feedback and response time metrics
• Overtime: Ensure the compressed schedule does not simply shift work to unauthorized overtime

Ground rules

• Meetings are reduced in number and duration
• Low-value activities are identified and eliminated
• Core collaboration hours are defined
• Employees are expected to maintain output standards
• The pilot can be adjusted or ended if significant problems emerge

Evaluation

At the end of the pilot, compare outcomes to your pre-defined success criteria. Be honest about both benefits and challenges. Gather qualitative feedback alongside quantitative data.

Legal and Compliance Considerations

• Overtime: In states with daily overtime requirements, a compressed 4x10 schedule triggers overtime pay after 8 hours. This may negate cost savings.
• Benefits eligibility: If reducing weekly hours below 30, review whether employees remain eligible for benefits under your plan and the ACA.
• FMLA eligibility: FMLA eligibility requires 1,250 hours worked in the preceding 12 months. Reduced-hour schedules may affect this calculation.
• Exempt employee considerations: Exempt employees must still meet salary and duties tests. Reducing their scheduled days does not affect their exempt status as long as they receive their full weekly salary.
• Equal application: If the four-day week is available only to certain roles, ensure the distinction is based on legitimate business needs, not factors that could correlate with protected characteristics.

Making the Decision

A four-day workweek is not universally appropriate, but it is worth serious consideration if:

• Your business is knowledge-based and output can be measured independent of hours
• Employee retention and satisfaction are priority concerns
• You are willing to invest in efficiency improvements and meeting culture reform
• Your competitive landscape makes it a meaningful differentiator for talent

The strongest approach is to pilot, measure, and decide based on evidence rather than ideology. The four-day workweek is a business model decision, not a political statement, and should be evaluated with the same rigor as any other operational change.
