Work is not a mere commodity. This chapter applies notions of commerce to individual and collective situations in the labor market (recruitment, promotions, careers, conflicts, statutory, and contractual relational systems, etc.), and hence to the commerce of oneself (that is, selling one’s time and skills to an employer). Ambiguity reigns between subject and object because of power relations and the bilateral instrumentality in the market employment relationship, but also because of the sociability that develops in a context experienced in common, which includes, inevitably and fortunately, a non-market side.
