More than half British workers claim they have experienced symptoms associated with over-work and burnout during the past six months.
A third of people questioned in a survey said they had experienced physical or emotional exhaustion, while 26 per cent said they had lost sleep or been ill as a result of worrying about work, according to human resources consultancy Hudson.
Just under half of employees said they thought the situation had got worse during the past five years.
They blamed the problem on the increased pace of business life and an increasingly competitive environment, coupled with more demands being made on fewer staff.
But while 92 per cent of employers said they thought burnout existed, just 35 per cent thought it was a problem in their own company and 59 per cent said they had no system in place to help a worker who was suffering from it.
About 14 per cent of HR managers said they had lost staff due to burnout, while 36 per cent said they had seen a decline in productivity and 79 per cent said there had been an increase in the number of sick days being taken.
The Survey Shop questioned 501 employees and 505 employers and HR managers by telephone.
