Fewer than two-thirds of employees (64%) are satisfied with their jobs, according to a new survey.
The poll of over 1,100 UK workers by Mercer Human Resource Consulting shows a reduction of 10% since the survey was conducted three years ago.
The number of employees who feel a strong sense of commitment to their organisation has also fallen 5% since 2002, to 59%.
Patrick Gilbert, head of organisational research and effectiveness at Mercer, said the employment market has become more buoyant in the past two years, so more employees are feeling restless and dissatisfied in their jobs.
“With more opportunities available, people often think the grass is greener elsewhere,” he said.
“When employment opportunities are limited, employees tend to have lower expectations and feel more satisfied with their jobs.”
