Yötyö

Yötyö is a Finnish term referring to work performed predominantly during the night hours. The exact span of “night” is defined by national law or collective agreements, but it typically includes a period roughly from around 21:00–22:00 to 05:00–06:00. Yötyö is a form of shift work and can be organized as fixed night shifts or as part of rotating schedules.

Common sectors where yötyö occurs include healthcare (hospitals and home care), emergency services, public transportation, security, manufacturing, hospitality, and media production. The scheduling of yötyö can vary from long-running night shifts to rotating patterns that alternate with day shifts.

Regulation and protections around yötyö are intended to safeguard health and safety. Employers are generally expected to assess risks associated with night work, ensure sufficient rest periods, and provide health surveillance where required. Many labor agreements include provisions on compensation or shift premiums for night work. Special considerations often apply to vulnerable groups, such as pregnant workers, and to younger workers, with rules designed to limit adverse effects.

Health and safety considerations are central to the concept of yötyö. Night work can disrupt circadian rhythms and sleep, leading to fatigue and increased risk of accidents. Protective measures include thoughtful rostering, adequate breaks, access to suitable rest facilities, appropriate lighting, and opportunities for medical checkups or health guidance.

In practice, yötyö intersects with workforce planning, family life, and social activity, and its management often aims to balance operational needs with worker well-being through scheduling practices and negotiated terms.
