For applicants employed as WiMis (scientific staff member), the terms of “The Act of Academic Fixed- Term Contract” (Wissenschaftszeitvertragsgesetz, WissZeitVG) apply. Science-Support Staff members are subject to the limitations of the German act on part-time and temporary work (Teilzeitbefristungsgesetz, TzBfG). Fixed-term contracts cannot be issued without reason (“Sachgrund”). Unfounded fixed-term contracts (“sachgrundlose Befristung”) are invalid.
