Substitute doctors or a locum doctor are physicians who support changing employers (clinics, practices, etc.) for a certain period of time on an hourly rate basis. This is possible within the framework of a temporary employment and an employee leasing (German: Arbeitnehmerüberlassung, short ANÜ).
The term substitute doctor is often used synonymously with fee-based doctor. However, fee-based doctors are or were freelancers, which has been legally restricted since June 2019 due to pseudo-self-employment and thus represents an employment subject to social insurance, for which one is also insured via the clinic. Since Taledo only places doctors in temporary positions, "substitute doctor" or "locum doctor" are the correct terms.
