Half of the UK's working population have admitted that they want to leave their job, according to a study by the London School of Business and Finance (LSBF).

Forty-seven per cent of the 1,000 of workers surveyed across the UK said they want to change their jobs, but stay in the same career. But more than one in five said they wanted to switch careers altogether.

The study found that workers believe they can find a better salary, job satisfaction and work-life balance if they jumped to a different career.

The UK's young workers, those aged 18-24, are the most likely to seek a career change, with 68% of those surveyed admitting they want a change. That figure drops slightly to 65% in 25-34 year olds.

It applies to just over half (52%) of 35-44 year olds. But those over the age of 45 are far less likely to want to change careers. The 45-54 year old category fell to 43% and just 19% of those aged 55+ want to switch.

LSBF found that younger workers are more likely to really regret their career choice, not simply based on salary or working hours but for the job itself. A quarter of all those surveyed admitted this, but 30% of those aged 25-34 year said that regretted their decision. Looking at millennials - those currently aged 18-34 - the figure rises to a massive 66%.

Workers in London are the least happy, with 55% wanting to switch careers, and 45% planning to do so in the next two years.

"With a changing economy and new sectors creating jobs and business models that would not have even existed a decade ago, many professionals may have considered the option of jumping ship and facing the challenges of a new career path," said Dr Steve Priddy, dean and director of research at LSBF.

"I’m particularly delighted to see that our younger workforce is bold enough to dare try to enter a new professional field."
