NEARLY a third of shopworkers are on the verge of quitting due to spiralling levels of in-store violence, threats and abuse, retail union Usdaw warned yesterday.

Around 30 per cent are considering a change of job and four in 10 feel anxious at work because of abusive customers, according to Usdaw’s latest annual survey.

The poll of more than 7,700 staff found that about three-quarters have suffered verbal abuse, up from 68 per cent in 2019 – and 49 per cent have been directly threatened, a 6 per cent increase on four years ago.
