What should I know about freelance work, project roles and bogus self-employment risks?

In Germany, freelance roles, service-oriented projects and traditional employment should be strictly categorised separately. Recommendation: supplement project roles with details on supervision, integration, duration and service type. In practice: describe project roles with information on duration, location, service type and degree of supervision. Limitation: not every long-term project role is automatically problematic.
