Present but not correct - Surfing the web, personal telephone calls, or cigarette breaks, excessive chatting in the office and the circulation of emailed jokes are all manifestations of "presenteeism" - when employees are present at work but are not working. Because of the clandestine nature of this subject, and perhaps because some organisations would rather turn a blind eye to the problem, very little research has been undertaken into presenteeism. Here, we tackle the subject by means of a detailed study of 41 organisations from across the private and public sectors. Our analysis reveals that: while the overall extent of presenteeism appears to be limited, some organisations acknowledge that they suffer badly from the problem: the majority of respondents to our research feel that presenteeism has a negative impact on key determinants of organisational performance, especially productivity, and concentration, although some believe that there can be beneficial effects in such areas as employee motivation and happiness: and organisations manage presenteeism in a number of ways, with the most common strategies including the use of policies governing employees' use of email or the internet.
