Questione giuridica chiave
Whether the insured person met the minimum contribution period despite on-call part-time work.
Decisione estratta
Yes. Under the case law, each calendar month in which work was actually performed within a single continuing employment relationship counts as a contribution month.
Motivazione estratta
The employment relationship lasted throughout the reference period, and the on-call assignments were made under one contract rather than separate contracts. Article 11(2) AVIV applies only when employment begins or ends during a month, which was not the case here.
