Sickness Rates Remain Elevated in 2025

According to an analysis by the Techniker Krankenkasse (TK), the rate of sickness-related absences among employees has remained high during the first half of 2025. The average number of sick days taken by employees from January to June was 9.5, a slight decrease from 9.6 days in the same period of 2024. However, this figure is significantly higher than the 7.8 days recorded in the first half of 2019.

The leading causes of sick leave continue to be respiratory illnesses, including common colds, bronchitis, and COVID-19 infections. TK's report highlights that the onset of the year saw a wave of colds and flu, contributing to the increased absenteeism. February, in particular, witnessed a higher sickness rate compared to previous years, with employees averaging 2.4 sick days due to these illnesses, up from 2.3 days in early 2024.

Following respiratory illnesses, mental health issues, such as depression, ranked as the second most common reason for taking sick leave, averaging 1.9 days per employee. Musculoskeletal disorders, including back pain and herniated discs, accounted for an average of 1.3 sick days per employee in the first half of the year. The analysis draws on data from approximately six million working individuals insured with the Techniker Krankenkasse.

This persistent high level of sickness absence raises concerns about the overall health and well-being of the workforce. Employers and policymakers may need to explore strategies to address these health challenges, including promoting workplace wellness programs and providing mental health support.
