Establishing the causal nexus on mental health/illness related to work is a new demand for psychology as a science and as a profession in all fields of activity. This text examines the interlocution between work and mental health/illness in the course of the history of psychology. It also presents some procedures referring to the diagnosis and the justification of the causal nexus between work and psychopathological illness. Even if we consider the causal nexus as a reductionism in psychopathological illness, this is a legal requirement to be recognized as an illness related to work and to obtain social welfare agency benefits.
