This thesis addresses the situation of brothel-based sex-workers, as seen from a labor-law perspective. After a survey of the relevant legislation and jurisdiction of the Supreme Court of Justice in the context of the provision of sex-services, it tries to depict the actual occupational conditions of sex-workers in general and in particular to their respective (brothel-)establishments and investigates the distinctive dependency of these labor-relations. Subsequently it tries to resolve the question, whether an employment-contract between brothel-operator and sex-worker can been conducted in accordance with the new Supreme Court jurisdiction, or if it still fails according to § 879 Austrian Civil Code (ABGB). Freelance employment-contracts and the so called worker-status similarity, which add even more connections for the implementation of labor-law-norms on sex-workers will be discussed thereafter. The Supreme Administrative Court jurisdiction of the foreign labor act (AuslBG) will be elaborated more precisely in conjunction with the worker-status similarity. Finally, a brief overview with respect to the handling of income taxation and social security of sex-workers is given.
