[SOLVED] Use interventions to mark teleworking ?

Hi,

I wish to allow my coworkers to mark some days as teleworking to share with the team.

I am not sure what the best practice would be for that. I am thinking of using a special task within an "internal project", with manual planning, and use the interventions feature.
But wouldn't that mark the resource as occupied ?
What is the best practice to handle a teleworking status, without impacting the availablity of a resource ?

Thx
Franck
