This paper examines how prolonged heat exposure affects the labor force's ability to work in the short and long run. We provide the first comprehensive characterization of the occupation-specific heterogeneity in how heat-induced health damages materialize in decreased labor supply and its distributional implications. To this end, we link administrative public health insurance records for one-third of the German working-age population to the quasi-experimental occurrence of heat waves. Our findings show that an average hot day increases the number of new sick leave cases by about 3.5%. With enduring heat exposure, the effect increases to 5.0% on the third day of consecutive heat stress and roughly triples to 10.8% after seven days. Workers who are already disadvantaged in terms of their income and working conditions are more vulnerable to heat stress. Those more flexible in scheduling and adjusting their working hours are less at risk. Our results also reveal a longer-term decrease in labor supply in the years following heat wave exposure and suggest sustained increases in the demand for healthcare services.
