WHAT IT FOUND

Employees who felt their work was appreciated and had good workplace atmosphere had the lowest sickness absence.

Those reporting worsening work ability and musculoskeletal pain had the highest risk of long-term absence, while cardiovascular risk factors predicted absence even when symptoms did not hinder work.

Key findings

01Employees in the 'healthy' cluster, defined by positive managerial performance and workplace atmosphere, had the lowest rates of both short and long sickness absence.

02Employees in the 'work ability' cluster, who reported deteriorating work ability and musculoskeletal pain, had the highest incidence of long-term sickness absence.

03Employees with cardiovascular and metabolic risk factors had an increased probability of long-term sickness absence, even though they typically reported that their symptoms did not hinder coping at work.

What it does not show

The study is observational and cannot prove that specific risk factors cause sickness absence; it only shows associations. Data came from a single Finnish occupational health provider, which may limit generalizability to other countries or healthcare systems. The clustering methods identify groups based on existing data patterns, which may not capture all nuances of individual employee experiences. There is substantial variation between individuals within each cluster, so these profiles should not be used to stereotype or automatically assign risk to every employee in a group.

The easy way to misread this

Do not assume that employees with cardiovascular risk factors are safe to return to work or do not need support just because they report no functional hindrance. This cluster had a significantly increased probability of long-term sickness absence, suggesting their risk may be under-recognized by the employees themselves.
