Durability of Protective Adaptation in Four-Day Workweeks

Determine whether voluntary employee effort and protective adaptation can sustain a four-day workweek over time or eventually erode it under conditions of high workload.

Background

The paper examines how a reduced-hour four-day workweek is introduced, adapted, institutionalized, and sustained in an agile software organization. Its proposed survival matrix identifies protective adaptation—such as voluntary overtime, temporary returns to five-day schedules, and intensified coordination—as a mechanism through which employees and teams absorb organizational and market pressures while preserving the four-day arrangement.

The authors note that participants already reported high workload, creating uncertainty about whether voluntary effort can remain sustainable over the long term. The unresolved issue is whether this protective adaptation provides a durable basis for maintaining the four-day workweek or eventually undermines it through cumulative workload and effort demands.
