Presenteeism or working while sick is the act or culture of employees continuing to work as a performative measure, despite having reduced productivity levels or negative consequences. Reduced productivity during presenteeism is often due to illness, injury, exhaustion, or other conditions, but presenteeism can also describe working while contagiously sick, which has the added risk of creating a workplace epidemic.
