For many women, being told to flirt to get ahead at work seems sexist and out of touch.
But research published in the Personality and Social Psychology Bulletin says it might be just the thing to do.
In the study women who used "social charm" - ie flirting - were rated as being more effective at performing everyday tasks than those who did not, with authors concluding it can help women win negotiations - either with their colleagues or in everyday life.
Lead author of the study, Berkeley Professor Laura Kray said in general women tended to be perceived as "strong" or "warm."
"Using feminine charm in negotiation is a technique that combines both," she says.
"The key is to flirt with your own natural personality in mind. Be authentic. Have fun. That will translate into confidence, which is a strong predictor of negotiation performance."
But some say while it might have worked for Madeleine Albright, it's inappropriate for women in this day and age. Laura Bates, of the Everyday Sexism blog thinks so.
"The reporting of these kind of studies as 'news' risk perpetuating harmful sexist stereotypes and could have a damaging impact on gender relationships," she tells The Huffington Post UK.
"The Everyday Sexism Project receives hundreds from accounts of women suffering harassment and gender prejudice on a daily basis, with many reporting that when they try to object they are blamed for what has happened as if they somehow invited the incidents because of their dress, for example, or behaviour.
"Within this context, it is extremely unhelpful to perpetuate the highly generalised notion that women as a group use flirting to their advantage in business transactions."
As for the study itself, Bates says "it seems to rely on a completely stereotypical and one-dimensional sexist assumption - that women are either 'strong' or 'warm' - and that 'warmth' in a woman must imply some element of sexual availability."
Jezebel aren't that sure either, writing that the research "hardly proves that women should start winking at their male peers; it just means women can get shit for cheaper if they flirt."
