In this time of economic uncertainty, a new survey finds that one in five employees said they would flirt with their superior if it meant they were more likely to get a promotion.
This is twice as many as admitted the same during the survey four years ago, with men most likely to go further with their boss.
One in four men said they would work their charm on their boss in order to get job security and a pay rise.
A third of men surveyed said they actually fancy their female bosses and are attracted to their strength, self-confidence and humour.
It seems that men are more are more open to dating in the workplace, with 57 per cent of them saying they would go out with a colleague, compared to just 15 per cent of women.
Commenting, Dr Nafsika Thalassis, a psychologist, said: "Perhaps women have learned through bitter experience that using one's sex appeal to get ahead at work can backfire.
"Women who flirt with the boss risk having their bluff called. They are more likely to realise that flirting to get ahead will be disapproved of by colleagues. Men are less concerned that flirting will result in being cornered by their boss.
"But they should be wary – hell hath no fury like a woman scorned. The fun of flirting lies in its maybe-I-mean-it, maybe-I-don't playfulness, but it is often better to conduct relationships with absolute clarity."
