This diploma thesis examines the areas of conflicts between administering poverty and secur-ing sustainable social work in low-threshold homelessness services. The thesis aims to illus-trate that day-to-day services in assisting people who are homeless always operate within this field of conflict. Due to present legal conditions as well as predominant stereotypes and social structures, social work can only operate within a limited framework. As a result, and because of material, sanitary and social disadvantages, certain groups of people are being excluded from the private and municipal housing market, and partly also from the Wiener Woh-nungslosenhilfe, a welfare organization that assists homeless people in Vienna. This circum-stance contradicts the Universal Declaration of Human Rights, which recognizes the right to housing as part of the right to an adequate standard of living. As a result, homelessness ser-vices are facing the challenge of ending homelessness, poverty and their side effects on the one hand, and administering poverty on the other hand. Social work is therefore often nar-rowed down to stabilization work and safeguarding human survival. Nevertheless, this type of social work, which mainly consists of performing administrative tasks, is important and essen-tial in order to secure sustainability in welfare work.
