The Index surveys employees on an annual basis, but this year City and Guilds surveyed businesses too, to see if there was a difference of opinion.

The study showed that employers scored their workers' happiness lower than staff rated it themselves. Over a quarter of firms thought financial incentives were key to their employees' happiness, but only 17% of workers agreed.

According to the Index, over two-thirds of workers are happy in their jobs. Workers in north east England are the happiest out of all regions. Unhappy workers include HR managers, secretaries, PAs and admin workers.
