presenteeism

1. (chiefly UK) The fact of being present at work, especially if one is too sick to be productive, or working beyond the expected hours.Examples: "Research shows that presenteeism, apart from the obvious danger of contamination of other workers, can lead to longer absence from work later on."; "Organisations that have noticed an increase in presenteeism are nearly twice as likely to report an increase in stress-related absence and more than twice as likely to report an increase in mental health problems among their staff too."; "Employers should guarantee sick pay, including for contacts of known cases, and do everything they can to discourage the practice of “presenteeism”."
