RISE: Is it possible to second staff who is not having an employment contract but has a cooperation agreement? In that case does the cooperation agreement have to ensure compliance with the RISE obligations (ex: full-time work, confidentiality, IPRs, use of resources, etc…see especially articles 6 and 32 of the GA) and be signed 6 month prior to secondment?

Any kind of contractual obligation, which fulfills the requirements (full-time equivalent for 6 months, confidentiality, IPR, possible reintegration, etc.) would be OK. The kind of contract/agreement depends much on national regulations and solutions in place at the host institution.
