This questionnaire-based cross-sectional analysis with 2037 Swiss general practitioners (GPs) focused on young GPs (≤40 years) and investigated which preconditions would allow them high satisfaction and low stress levels in their work. Young GPs (n = 206) are more often female (57 %, p <0.001), 46 % are employed, have a lower workload (38.2 vs. 44.0 hours per week, p <0.001) and plan significantly more often consultations of 30 minutes (p = 0.006) than older colleagues. Under 40-year-old GPs were more satisfied with their work situation (p = 0.046), but had a higher stress level (p = 0.01) compared to GPs >40 years of age. Administrative tasks tend to increase stress levels (p = 0.054). Knowing the problems of the young GP workforce is essential to securing the next generation of physicians.
