The petition is part of Usdaw's Freedom From Fear campaign and was delivered by Usdaw deputy general secretary John Hannett and four retail workers who have been victims of violence and abuse.
Hannett said British Retail Consortium figures showed shopworkers had faced 16,200 physical assaults, 48,600 threats of violence and 70,000 incidents of verbal abuse last year. "The BRC's statistics underline what we have been saying for some time violence and abuse against shopworkers has reached intolerable levels.
"The petition is just one step in our ongoing campaign to get employers, the government and the police to take retail crime much more seriously," he said.
The union has also launched a Shopworkers' Charter and has organised a National Respect Day for shopworkers on September 17.
