We propose a model (see attached, in German) for our goal of permanent employment for scientists who raise their own funding. The individual risk would be insured by TU Wien. With our model, a comparatively large number of permanent positions can be created at TU Wien for a modest expense.

Paragraph 109 UG (University Law) updated in 2021 enforces a change of institution (often abroad) or an end to the scientific career if there is no permanent employment. Several hundred scientists of all ages are affected by this at TU Wien. In particular, there are also scientists affected who successfully acquire third-party funding for themselves and PhD positions. These scientists are professionally established, have research experience, and are well-networked. Their leaving would seriously damage TU Wien and affect its attractiveness as an employer.
