Its survey of over 1,000 UK employees found that 49% admitted to lying in the workplace, with reasons for doing so including to avoid getting into trouble (44%) and to hide mistakes (34%).
Some employees have done so in order not to stand out rather than lying for their own personal gain.
Forty per cent said they had lied because it was easier to agree with the majority, while 24% said they had done so because their boss or colleagues do not like to hear diverse opinions. A further 17% said they have lied because they do not like giving honest feedback to colleagues.
While 39% of those surveyed said lying is commonplace where they work, the study found that there is a wide range of motivations for doing so.
Glassdoor EMEA director Joe Wiggins said the findings begged the question as to whether enough employers are encouraging an environment where people feel comfortable with transparency.
“If there is a culture of peer pressure or an environment where diversity of thought is not valued and nurtured, this leads to people masking their true feelings, which could lead to more systemic deceptions as well as bias.”
Only 22% of respondents said that lying at work is acceptable, but 69% said that telling a 'white lie' at work to spare someone’s feelings is not problematic.
Additionally, 75% of employees asked said they believe that saying what you really think at work can get you into trouble, while 56% said they hide their true feelings at work.
Speaking to HR Magazine, Liz Sebag-Montefiore, co-founder and director of 10eighty, pointed out that there is a perceived difference between lying and withholding information.
“People want to protect themselves. There's a lie and a white lie – as long as you're not being dishonest, withholding information I think people think is ok.
“Particularly during coronavirus, there has been a lot of withholding information happening about how people are actually feeling about going back to work. Somebody might tell a lie because they don't want to let anyone down, they feel they should say yes even if they don't feel comfortable about [returning to work].”
She added: “[Employers] need an open and honest culture; it's not around blame, it's around the learning from it.
“If you've got that culture where it's all around learning from your mistakes, people are going to be willing to admit them, whereas if it's all around blame and a culture of a manager not having a coaching style but having a direct command and control style people aren't going to be willing to come forward with their mistakes, they're more likely to bury them.”
The survey, which was conducted by OnePoll on behalf of Glassdoor, was carried out between 23-24 June 2020.
