International audience Should I stay or should I go? Young PhDs access to employment. The follow-up survey of young PhD graduates carried out by a French university coupled with biographical interviews makes it possible to analyze their trajectories of access to employment. These trajectories are rarely linear. While the main project when beginning PhD thesis is academic career, its access implies strong geographic constraints on the private sphere of the individuals. We observe a diversity of configurations showing the tangle of professional, personal and geographical dimensions.
