A survey of 5,919 managers by the Chartered Management Institute found IT staff were more likely to work on holiday than managers in any other industry.
According to the survey, 48% of IT managers checked their work e-mails when on holiday, compared with 47% of managers in financial services and 18% in the public sector. And over 60% of IT managers monitored their work voicemail, compared with 42% of financial services managers and 18% of public sector managers.
"We wanted to show there's a problem with people's ability to switch off. If you are refreshed, you are better at your job," said CMI spokesman Mike Petrook.
IT managers gave the fear of missing deadlines as the main reason for working during holidays. Almost 40% of them blamed short-term deadlines for the need to work during holidays. One-third blamed the need for general care for their clients and 26 % the fear of a backlog of tasks.
Petrook advised managers, "Be more confident in delegating to people. Recognise that if there's an emergency, they will contact you."
