This study is aimed at updating the knowledge on case records of workers examined at the "Center for Occupational Stress and Harassment" of the "Clinica del Lavoro Luigi Devoto" in Milan. A sample of patients examined between 2009 and 2011 (n = 198) was compared with a sample examined in 2003 (n = 226). Compared to the past case records, the latter sample included a significantly higher number of graduates (chi2 = 6.6; p < 0.05) and managers (chi2 = 21.5; p < 0.01), employees from the private sector (chi2 = 11.3; p < 0.01), trade (chi2 =22.6; p < 0.01) and micro/small enterprises (chi2 = 41.9; p < 0.001). Company changes and organizational conflicts were the main antecedents for workplace bullying.
