What should I know about exception rules and borderline cases?

In the DACH context, pay transparency, the General Equal Treatment Act (AGG) and contractual clarity are crucial for exception rules and borderline cases. Recommendation: document salary fields, band logic and exceptions in the portal in an audit-proof manner. In practice: example 2 -- review cycle with audit log, KPI tracking and escalation path. Limitation: overly generic rules without role or legal context reduce quality. (Sources: EU Directive 2023/970 Pay Transparency, Destatis Labour Market)
