Research commissioned by outsourced Internet operations company Attenda showed that nine out of ten IT managers exceed the 48-hour working week specified by the European Working Time Directive.
According to respondents, the top reason for the extra hours was a lack of resources (28 per cent), followed by pressure of development work (22 per cent). Some 14 per cent said they were called on for "out of hours" support calls and 10 per cent cited "tight or unrealistic deadlines" as the cause of extra hours worked.
The results were consistent across the country and by industry sector. Those in the south, excluding London, are most burdened by extra hours with 95 per cent working beyond the standard week, closely followed by the Midlands 88 per cent, London 86 per cent, Scotland 75 per cent, and the north 71 per cent.
The Government sector was the hardest hit of the industry sectors with all respondents saying that they worked beyond the standard working week.
This was closely followed by retail 93 per cent, education 89 per cent, finance 87 per cent, manufacturing 86 per cent, and hi-tech, 86 per cent.
