Too many IT managers work during their holidays, according to a survey by the Chartered Management Institute (CMI).
The CMI questioned 6,000 managers across different industries and found that IT managers were among the worst at letting go.
Almost half (48%) regularly checked their work e-mails and 61% monitored their voicemail while on holiday. Many left their holiday contact details behind and rang the office to check things were OK while away.
Asked why they worked during their breaks, IT managers cited short-term project deadlines (39%), client care (30%) and the fear of backlogs when they got back (26%).
Jo Causon, CMI director of corporate marketing and IT affairs, said, "The hours people put in at work do not always guarantee optimal results, because quantity is not the same as quality.
"Employers are certainly beginning to recognise this and are encouraging staff to take a proper break, but the onus must now be on managers to follow this lead."
The CMI found that IT managers in the North East were the least able to forget the office when on holiday, and those in the North West were best at it.
