The recurrence of employee suicides caused by stress has highlighted important questions about current management methods. The link between suicide and work remains unclear. However, a general consensus seems to be emerging around this debate. In less than half a century, there has been an explosion in the number of articles devoted to the phenomenon of stress at work in the professional press, as well as investigations and reports, all of which testify to a general awareness. The rapidly changing world of work is said to be the source of a new stress, more deadly than ever before. The seriousness of the phenomenon has prompted us to take a closer look at this risk in the workplace and its repercussions on the individual. More specifically, we are going to look at stress factors and examine a potential determinant of stress: the imbalance between effort and reward (Siegrist, 1996).
