Departing technical director Sam Michael's last Grand Prix with the Williams race team will be Korea in October.
Jacques-Armand Dupuis, writing for France's autohebdo.fr, reported that the Australian is not sure if he will then revert to a factory-based job or be sent on 'gardening leave' as the British team looks ahead to 2012.
"Most of the technical directors go to the races, but the (new) structure at Williams means that he will not.
"Mark Gillan is the chief engineer and he will be in Japan and Korea and he will then take my place," said Michael, who has been linked with a move to Force India.
Dupuis reported that moves to Mercedes and Ferrari have also been touted for the 40-year-old.
"Everything is open for the future," insisted Michael.
Meanwhile, after Williams experimented with a no-KERS configuration for Rubens Barrichello at the Nurburgring, Michael confirmed that the energy recovery technology will return to the Brazilian's car this weekend.
