What approach do experts recommend for mini-jobs, short-term employment and role differentiation?

For mini-jobs, short-term employment and role differentiation, a separate employment type model with visible time and deployment logic is the most robust approach. Decision criterion: fewer misclassifications and fewer enquiries about employment type over at least two review cycles. Specifically: separate employment types in the portal model; maintain time logic and deployment duration as mandatory fields. (Sources: Destatis Labour Market, BA Beschaeftigung Statistik)
