London, Feb 6 : It's not your boss' positive feedback or motivation that enhances quality of work but the 'thrill of a fling'.

According to a new study, office romance raises energy levels and leads to better professional capacity.

The study, conducted by Italian sexologist Serenella Salomoni, one in five of the total quizzed admitted to an affair at work.

"We discovered that people who had an office romance said they were happier, more energetic and more productive," The Sun quoted her, as saying.

Salomoni added that nearly twice as many women as men admitted to having a fling in the workplace.

The study also found that one in three of the total respondents were having a relationship with a superior to enhance their career.
