Ever-increasing workloads and long hours mean more than half of employees cite work as the biggest cause of stress.
The pension and benefit consultant JLT Employee Benefits found 55 per cent of 120 people surveyed thought work was the most stressful part of their life, followed by money at 19 per cent and family at 13 per cent.
Just 10 per cent of people said that relationships were their biggest cause of stress, with health coming last at just three per cent.
Adrian Humphreys, group risk and health director for JLT Employee Benefits, said: "The results illustrate the huge part that work plays in our lives, and the resulting risk of exposure to work-related stress caused by issues such as ever-increasing workloads and long hours."
"Employers need to address stress by identifying and managing the key contributing factors within the workplace, as well as giving employees the tools to identify and obtain support for any mental health issues they are experiencing.
"Reducing workplace stress is not only good for employees, but employers will see the benefit too as productivity increases and staff turnover is reduced. It really is a win-win situation for everyone."
