Germany is preparing to tighten its rules on medical certificates for sick employees, but researchers who study the country’s rising absenteeism rates argue the government may be targeting the wrong cause. They point instead to mental health pressures and worsening conditions in fields such as nursing, care work and teaching.
German workers took roughly 22 sick days on average in 2024, one of the highest rates among wealthy nations. The figure comes from BKK, an association representing company health insurers, and it jumped in 2022 after Germany introduced electronic sick-note reporting, a shift that captured short-term absences more accurately than the paper system it replaced.
Chancellor Friedrich Merz’s coalition wants to scrap telephone sick notes and let employers demand medical certificates starting on the first day an employee calls in sick. Officials frame the change as part of a broader effort to lift productivity in an economy dealing with an aging workforce and years of sluggish growth.
Where the sick days concentrate
Researchers who study labor markets and mental health say the absenteeism data points somewhere specific: professions marked by chronic understaffing, low pay, thin career advancement and heavy emotional demands.
BKK figures for 2024, the most recent year with sector-level breakdowns, show women in healthcare and social work took 27 sick days on average and teachers took 24. Workers in finance took 18 and those in communication took 16.
Johannes Siegrist, an emeritus professor at the University of Duesseldorf, said the underlying issue often falls short of a clinical diagnosis. “It doesn’t need to be a full-blown depression,” he said. “It can also be a state of exhaustion or burnout as a result of problematic working conditions.”
Mental disorders account for just 4.8% of sickness cases, according to AOK, Germany’s largest health insurer. But when they do occur, they lead to an average of 28 days away from work. AOK data also shows sick days linked to mental health issues among its members have climbed 47% since 2014, making mental health the second-largest driver of absence after respiratory illness.
A mismatch between demands and rewards

Siegrist described the specific strain facing healthcare, education and social services workers as a combination of high responsibility and low compensation. “They have jobs with high responsibility, they need to combine task performance and social interaction and they have to deal with emotional problems, but also with physical stressors, including violence,” he said. “And often these are low-paid people with a rather low socioeconomic status.”
Occupational health scholars have a term for this pattern: effort-reward imbalance, where employees face intense demands without corresponding pay, status or job security. A substantial body of international research links that imbalance to mental health problems and extended absences from work. It has also been tied to a higher risk of coronary heart disease.
Germany’s schools show the pattern clearly. The 2024 German School Barometer found that nearly half of teachers reported psychological or physical violence among students at their school. More than a third said they felt emotionally exhausted several times a week.
Nursing shows a similar strain. Staff shortages remain acute across the sector, yet recent German studies have found wage growth has stayed limited, particularly in hospitals and public institutions, even as the workload on remaining staff intensifies.
Germany’s health ministry declined to comment when asked why absenteeism runs highest in the sectors facing the heaviest mental health and emotional pressures.
Little evidence of abuse
None of this means mental health alone explains Germany’s absenteeism levels. Sick leave rates depend on a mix of factors, including demographics, workplace conditions, social norms and differences between national institutions, which makes comparing countries directly difficult.
Germany’s sick-pay system is also among the most generous anywhere. Employers replace 100% of wages starting on the first day of illness, for up to six weeks. Even so, seven OECD countries, Norway, Slovenia, Spain, Finland, France, Portugal and Belgium, report higher rates of sick leave among full-time employees than Germany does.
Sofia Malinai Domagk, a researcher at the OECD, said sick leave rules explain only part of the picture. “What we can say is that sick leave rules are one factor among many, and we would caution against reading too much into direct country comparisons of sick leave rates,” she said.
Researchers who have examined Germany’s absenteeism increase say they have found little sign of widespread abuse of the system. A joint study by the health insurer DAK and the IGES institute concluded that the sharp rise in recorded absences in 2022 came mainly from improved electronic reporting combined with unusually strong waves of respiratory illness and COVID-19 infections. Sick day totals have leveled off since then.
The same study found no evidence that telephone sick notes, introduced in 2020 during the pandemic, contributed to the surge. Researchers concluded that neither phone-based certification nor routine misuse of the system accounted for the record sickness levels recorded in recent years.
Enzo Weber of the Institute of Employment Research summarized the findings directly. “The available scientific studies suggest that sick leave by phone has not led to an increase in sick leave reports,” he said.
Unions and doctors push back
The government’s proposed changes have drawn criticism from Verdi, the services union, which said the plan reflects a “culture of mistrust” toward workers. Associations representing doctors said requiring certificates from the first day of absence would be “absolutely disastrous” for medical practices already stretched thin.
Facing that pushback, the government said it would give companies flexibility. Employers can choose whether to adopt the new first-day certificate requirement or stick with the existing rule requiring a doctor’s note starting on the fourth day of illness.
The debate leaves Germany with an open question. Whether tighter documentation requirements can meaningfully reduce absenteeism remains unproven, while the sectors driving the country’s sick-leave numbers, healthcare, education and care work, continue to face the staffing shortages, pay stagnation and emotional strain that researchers say sit at the root of the problem.
