I always struggle with the German word "Tarif", which I realise strictly speaking means a collectve bargaining agreement.

However, in my sentence, which is in a Corporate Policy for employees who are to be deployed abroad,

Für Tarifmitarbeiter wird der Ausgleich unter Berücksichtigung der gesetzlichen, hilfsweise der lokal üblichen Arbeitszeit im Tätigkeitsland ermittelt.

it strikes me that Tarifmitarbeiter, in this sense, is something much more straightforward. But "Tarifmitarbeiter" as opposed to what. What are the "non-Tarifmitarbeiter?"

Could it means just straightfoward "employees", "salaried employees", "union employees", "standard employees".....or what is the term "Tarif" meaning in this context?

Grateful for any enlightenment in advance :))))
