Part-time individual fellowship (IF)

Dear colleagues of the France chapter, 

I am an incoming Marie Curie Individual Fellowship holder, to be based in Paris. I read somewhere in the European Commission's documents that once the project starts, an individual fellow could request to carry out the project on a part-time basis for family/professional reasons. If you have done/are currently doing your IF part-time, would you mind sharing your experience? Notably, how did you negotiate a part-time contract, how is the salary calculated, and how did your host institute calculate the extension of your contract beyond the 24 months for a full-time employment?

Many thanks in advance!

Cheers,

Zi
