So-called ‘presenteeism’ has hit a record high, according to new research from the Chartered Institute of Personnel and Development.

The survey of UK employers found that there has been a three-fold rise in workers heading into the office, despite being unwell, since 2010.

The author of the study, Rachel Suff, said: “If people are coming in to work when really unwell it means that they are not performing and not adding value to their job, while their own condition could worsen or they could pass it to other workers.”

A total of 1,021 employers, who collectively employ 4.6 million UK workers were questioned for the study. Of those questioned, 86 per cent said people still came to work, despite being ill. The equivalent figure in 2016 was 72 per cent and in 2010 it was 26 per cent.

Meanwhile, research published by the Office for National Statistics (ONS) has similarly found that the number of sick days taken by UK workers has plunged to the lowest level since 1993.
