This article investigates the experiences of mobility and work transition for some "trailing spouses" following their partners in professional overseas assignments. It draws upon in-depth interviews conducted in Switzerland both with female and male accompanying spouses, in order to illustrate some aspects characterizing the subjective experience of precarity for these people living a mobile life, when career trajectories and occupational identities are interrupted, unstable, or altogether reimagined. The meaning of "precarity" will be discussed from a combined sociocultural psychological and anthropological perspective, through a look at the socioemotional relations involved and at the role of imagination.
