“…Greater depth could be given to our study by investigating individual proneness factors such as physical or mental illnesses. Previous studies on absence proneness, based upon long absence aggregation periods such as those we investigated, confirmed that many occupational, social, cultural, and individual factors affect the propensity to be absent [Johns, 2008]: for example, perception of illness [Giri et al, 2009], health-related behavior [Laaksonen et al, 2009], previous mental/behavioral and physical disorder [Reis et al, 2011;Roelen et al, 2011], socioeconomic conditions [Lu et al, 2010], work-family conflict [Jansen et al, 2006], and coping strategies [van Rhenen et al, 2008]. Perceived absence legitimacy is also a significant cause of absence [Johns, 2011].…”
