One out of four people admit to swearing at a co-worker, but new research shows that letting the expletives fly might not be a good idea.

64 percent of employers think less of employees who swear at work and 57 percent also said they would be less likely to promote a worker who swears in the office.

A majority of bosses said that cursing at work brought an employee's professionalism, control, maturity and intelligence into question.

But still, 51 percent of workers admitted cursing in the office. 95 percent admitted they do it in front of their co-workers and more than half said they do it in front of their bosses.

Workers also said they cleaned up their language in front of senior leaders and clients.

54% of men swear at work, while 47% of women do the same.
