“…On this basis, we calculated the sickness presenteeism prevalence as the percentage of participants having shown presenteeism during the 12 month before the survey. Further, sick days were determined as the sum of presenteeism and absenteeism days ( Gerich, 2016 ; Lohaus and Röser, 2019 ). Sickness presenteeism propensity, which reflects an individual’s probability of opting for sickness presence rather than sickness absence in the case of illness ( Gerich, 2016 ), was computed as presenteeism frequency divided by the number of sick days ( Biron et al, 2006 ; Gerich, 2016 ; Lohaus and Röser, 2019 ).…”
