In general, Austrian social security covers all persons who work in Austria. However,
                  not all workers contribute to every program. For example, students who work contribute
                  only to the Worker's Compensation program and people who receive a social insurance
                  pension contribute only to health insurance.
               
               Covered employees, their employers, and covered self-employed persons are subject
                  to compulsory contributions that are based on a percentage of their earnings.
