Restaurant operators must embrace the five principles of happiness to encourage sales and improve staff performance. That is what delegates at M&C Report’s Restaurant Conference were told today by Nic Marks, founder of The Centre of Well Being. He claimed happy workers in complex jobs could lead to 25% increase in a restaurant group’s profits. He said happiness caused a wider field of vision, which would enable guests to fully appreciate their restaurant experience and staff would pick up on service issues at an earlier stage. The five principles of happiness are: connect; being active; take notice, take notice and giving. Marks said that using the five principles as a barometer for recruitment would also see a drop in absenteeism and staff turnover. He said: “It doesn’t need to be expensive to do either.”
