The link between an employer and an employee is far more complex then what’s stated on the contract. Both parties have a whole set of unwritten expectations that they consider to be part of the deal. And to not meet these expectations can turn into a source of conflict. That has been Professor Denise Rousseau’s field of research for about 30 years now. She calls it the “psychological contract”. Xerfi Canal had the chance to meet her after her conference at la journée de la FNEGE to find out more, and to ask her what she thinks about what could be considered as a case study: the battle between trader Jérôme Kerviel and the Société Générale bank.
