Just over one in ten employees took time off for seven days in a (24) Of these, 9.5 per cent were ill for a week on more than one occasion. In Britain, employees can take sick (25) for up to a week before they have to produce a medical certificate. Owner-managers were far less likely to be off sick than their staff: 3.3 days on average, compared with the 10 days taken by employees.
