Those who have been convicted would have restriction orders placed against them in a bid to prevent repeat and violent offending.
Customers can also expect to see more police officers at retail hubs as they scan for knives and conduct other high-visibility operations under the NSW government's retail crime strategy.
The plan has been welcomed as workers continue to face intimidation, threats and violence during their shifts.
"We've had enough of retail workers being treated like punching bags," Shop, Distributive and Allied Employees' Association NSW secretary Bernie Smith said.
A nationwide survey of more than 10,000 retail workers across nine subsectors in August showed almost eight out of 10 are at high risk of harm from psychosocial hazards.
The hazard of customer aggression was second only to inadequate staffing, according to the workers.
Almost 190 people have faced 239 charges since the NSW government introduced new offences and penalties in 2023 for those who threaten, abuse or assault retail workers.
Those convicted could face up to 11 years in prison.
The Victorian government has foreshadowed similar legislative changes due to be introduced before year-end.
The NSW retail ban strategy also targets theft - 1080 people have been charged with more than 1395 offences over $960,500 worth of goods since August 2024.
"Retail crime is at a crisis level in Australia, with a ripple effect on every retail worker, business owner and retail customer," Australian Retailers Association chief executive Chris Rodwell said.
Retailers will receive safety packs and site assessments from the state government.
It will also hold monthly meetings with NSW-based retailers to discuss threats and issues.
"No one should be attacked for simply doing their job," NSW Police Minister Yasmin Catley said.
"Violence and aggression towards workers is intolerable and the presence of police tells people in no uncertain terms that this behaviour will not be tolerated and there are real consequences for those who cross the line."
The plan was developed in consultation with the union and retail industry.
