Presenteeism
Presenteeism or working while sick can cause productivity loss, poor health, exhaustion and workplace epidemics. While the contrasting subject of absenteeism has historically received extensive attention in the management sciences, presenteeism has only recently been studied.
Certain occupations such as welfare and teaching are more prone to presenteeism. Doctors may attend work while sick due to feelings of being irreplaceable. Jobs with large workloads are associated with presenteeism. People whose self-esteem is based on performance, as well as workaholics, typically have high levels of presenteeism.
