New research has discovered a link between sitting down at a desk all day and obesity.
Researchers at the Harvard School of Public Health in the US conducted a study which examined the work and exercise habits of employees across the European Union.
It was found that traditional diets have been replaced by shop-bought lunches which are high in saturated fats. This is causing weigh-gain among many people.
Similarly, a lack of places for employees to store their own food is contributing to the problem.
Athena Linos, an epidemiology lecturer at Athens University, said: "A basic cause of obesity related to the workplace is a lack of awareness of how serious this issue is among employers and employees."
In other employee health news, a study published by the American Journal of Epidemiology last month suggested that middle-aged employees who work longer hours often have poorer mental skills.
