Predictable Shift Work: How Reliable Shift Schedules Retain Employees

Why is predictability a decisive factor in shift work?

Hardly anything demotivates shift work employees as much as short-term changes to working hours. The so-called "calling in from days off"—meaning spontaneous deployments on planned rest days—is still common practice, particularly in healthcare, logistics, or production.

In his article "Predictability is very important for employees" (HR Performance 3/2021), Dr. Andreas Hoff shows that predictability is a central element of job satisfaction—and the key to long-term employee retention.

Why is traditional scheduling no longer enough?

Traditional shift schedules are usually created on a monthly basis. Changes occur ad hoc, often without consulting employees. This form of planning disregards the growing desire for self-determination and predictability.

According to Hoff, scheduling therefore needs to be structurally rethought—through a two-stage approach that combines flexibility and reliability.

How does a two-stage planning process work?

The model consists of:

1. Basic planning (long-term planning) – it defines the framework and secures staffing requirements.
2. Weekly planning (detailed planning) – it is updated on a rolling basis and bindingly finalized by Wednesday of the previous week at the latest.

Employees can submit preferences until shortly before the planning deadline. Once weekly planning is finalized, changes are only possible by mutual agreement.

What benefits does two-stage planning bring for employees and companies?

Employees gain:

• Predictability for the entire following week,
• Opportunities to influence their own working hours,
• Protection from short-term changes,
• and more control over leisure time planning.

Companies benefit from lower sickness rates, higher reliability, and a better working atmosphere.
