According to a study, having the flat-rounded bread at work can boost your productivity levels.
In a study led by American psychologist Dan Ariely as part of his book, Payoff: The Hidden Logic That Shapes Our Motivations, it transpired that handing out pizza at work was more likely to incentivise office workers than a cash bonus, The Independent reported.
The study was conducted at a semiconductor factory at Intel in Israel. Mr Ariely sent three different 'promotional messages' to workers in a bid to motivate them to get the most work done.
In the series of messages, the first offered them a cash bonus worth $30, while the second said their boss would compliment them and the third promised a voucher for free pizza.
Within a day, the free pizza proved to be the most motivating message, with productivity levels showing an increase by 6.7 per cent.
The compliment message proved as another motivating booster for the workers, increasing productivity by 6.6 per cent.
Interestingly, the cash bonus motivated workers by just 4.9 per cent. In fact, after two days those who received the money offer were 13.2 per cent less productive in the office.
By the end of the week, Mr Ariely noticed that productivity levels for the cash bonus category had dropped by 6.5 per cent in total.
As productivity levelled out over the course of the week, it turned out that compliments were actually marginally more motivating than the free pizza message overall, reports Asian News International.
