Single, female 30-somethings are the most unfulfilled at work, according to a new survey.

Unmarried and single women aged between 34 and 44, and living in the West Midlands, are most likely to feel unfulfilled in the workplace, according to research by ethical volunteering organisation Global Vision International (GVI).

The report also found that one in six British workers feel unfulfilled at work, with 43 per cent hankering to help those less fortunate than themselves; whilst 17 per cent go one step further and cite saving the planet as the only way to attain fulfillment.

Unsurprisingly, money also ranked highly with 54 per cent saying that earning more cash would increase their fulfillment, while 30 per cent think that more responsibility in the workplace will make them happier.

Just under a quarter of fed-up workers have ditched the office and taken a sabbatical, and according to GVI, the overall trend for taking sabbaticals has doubled.

Andy Woods-Ballard, a director at GVI, commented: "While it is worrying that so many people find their jobs unfulfilling, it is encouraging that people are developing a green conscience and wanting to volunteer to make a difference.

"It's interesting that those in the 34 to 44 age group were the most likely to feel unfulfilled at work as this is the age group that we are seeing the biggest rise in volunteers year on year."
