Almost half of workers feel uncertain and negative about the future because of Britain's Brexit vote, a new study shows.

A survey of 1,000 adults in the UK revealed that young workers and public sector employees were particularly pessimistic about the future.

One in five of those surveyed by the Chartered Institute of Personnel and Development (CIPD) said they felt they should update their skills because of the vote to leave the EU.

The research also revealed that some employees had witnessed bullying and racist incidents relating to the referendum result.

Ben Willmott, of the CIPD, said: "This survey shows that Brexit has proved to be a seismic event in people's working lives and reveals that there is significant level of pessimism in the immediate aftermath of the vote.

"Hopefully, as the political and economic situation becomes clearer, this will subside, but in the short term there is a clear need for UK employers to do more to engage with their workforce about the likely effects of Brexit on their organisation."
