Most workers in the UK (64%) are satisfied with their job, however 11% report feeling miserable at work, according to a study from the Chartered Institute of Personnel and Development.

The study, which surveyed more than 6,000 workers, aimed to measure job quality in the UK. CIPD’s study also found that 18% of workers who were surveyed reported being dissatisfied at work. A quarter, or 25%, feel their job negatively affects their mental health, while 30% say their workload is too much.

CIPD also found that 28% of senior leaders say that they find it difficult to fulfil personal commitments because of their job. Meanwhile, 27% of workers say that their job does not offer good opportunities to develop their skills. This increased to 43% among unskilled and casual workers. Among those in low-skilled jobs, 37% say they have not received any training over the last year.

Jonny Gifford, senior adviser for organisational behaviour at the CIPD, commented, “In terms of overall solutions, the message is clear: healthy workers are happy and productive workers. If there’s one ultimate aim in job quality it should be to improve the well-being of our workers.”

“More extensive training and development must be part of the solution, so workers can develop in their careers and feel more fulfilled in their work,” Gifford said.
