While I understand the point you are trying to make (CERN is partially on Swiss territory), it is not a Swiss employer by any stretch of imagination: they have extra-territorial status, like the UN.
Swiss laws and wages don't apply to CERN (workers there also don't pay taxes, or contribute to Swiss social welfare).
Its annual budget is about 1 billion _swiss francs_.
La Suisse pourrait contribuer à améliorer les conditions sociales des travailleurs détachés du CERN. Le Conseil fédéral est prêt à évoquer la question avec l'organisation.
