How do I implement mini-job, short-term employment and role differentiation in practice?

In Germany, mini-jobs, short-term employment and regular roles should be maintained in separate categories. Short-term roles with clear duration rather than just a side-job label. Mini-jobs in their own category and not mixed with part-time. Note: mixed models or changes in employment type require additional logic. (Evidence: Destatis Labour Market, BA Beschaeftigung Statistik)
