SE: Is a PhD student required to terminate a parallel employment contract during their secondment if this contract is synergic with the Staff Exchanges project they participate in?

If the activities under the employment contract are synergic with the MSCA Staff Exchanges project, the fellow could retain their current working arrangements, contract, and PhD stipend. However, if the activities under the employment contract are not synergic with the MSCA Staff Exchanges project, or if they result in double funding, then these working arrangements should be modified to ensure full commitment to the MSCA Staff Exchanges project during the secondment.
