Is it possible to implement a PF and chair a COST action at the same time?

With the approval of REA and the host organisation, it is possible to opt for part-time for professional reasons – if the researcher wishes to keep both projects, they should first ask the host if they agree, and then approach the project officer with this request. If approved, the PF duration will be extended (the person-months remain the same) and the unit costs reduced proportionally (i.e. the same amount of funding will be stretched over a longer period).
