ROTATE THE SHIFT
A stable body clock is a personal preference the schedule should not have to accommodate.
Rotate employees across days, evenings and nights to distribute inconvenience fairly. Change the timing often enough that nobody becomes excessively attached to a single sleep pattern. Call the arrangement operational flexibility.

Unfortunately, the research…
Claim
Shift work, particularly rotating and night schedules, is associated with sleep disturbance and can worsen sleep and mental-health outcomes, although effects vary across schedules, occupations and individuals.
Evidence
A 2026 systematic review and meta-analysis found shift work associated with higher odds of sleep disturbances, including for rotating shifts. A 2024 review of new shift workers found sleep and mental-health outcomes worsened after transition to shift work.

The Directive is satire. The research summary is not. Evidence is stated separately and qualified to the underlying literature rather than treated as proof of the joke.
