Despite 3m Britons buying a wearable device in 2015, we are not willing to use them at work, according to new research from PwC.

In a survey of 2,000 workers across the UK, only 46pc of people said they would accept a free piece of wearable technology if their employers had access to the data recorded.

This was despite the fact that two-thirds of respondents wanted their employer to take an active role in their health and well-being. The biggest barrier to adoption was trust, with 40pc saying they don’t trust their employer to use it for their benefit, and in fact believe it will actively be used against them.
