UK workers change their identities at work in order to get ahead, according to a study by Vodafone.

The annual Working Nation study found that 59% of workers change some aspect of their personality at work, while 6% change everything about themselves.

It found managers are driving the trend, with 67% of senior directors admitting they expect a reasonable level of identity change in the workplace. More than 50% of employers agree that the higher someone climbs within an organisation, the more personal compromises they make to their character.

Women are more likely to change their personality than men, and workers in the media and marketing sectors are most likely to change their identities in the workplace.

The study found that graduates feel under the most pressure to adopt a work persona, 60% believe they must change their behaviour to gain acceptance at work.
