Almost half of employees think they are doing the work of more than one person, according to a new survey.
Research by Mercer Human Resource Consulting found only 55% of people believe there are enough people in their department to handle the workload.
However, two-thirds of the 1,000 people surveyed said they could still maintain a work-life balance.
Managers once again were found lacking as half of the respondents said their managers did not understand the problems employees experience in their jobs.
David Tong, head of consulting at Mercer, said that managers are often too caught up in day-to-day pressures to listen to their employees.
“But if staff do not feel their managers support or empathise with them, they are likely to become frustrated and disaffected,” he said.
