Countdown has been called to act on security, as more than 70 per cent of union members report experiencing aggression from customers.
First Union met with Countdown senior managers yesterday to discuss security concerns, including the need for store-by-store measures, following last week's stabbing at Countdown Dunedin Central, which left four people hospitalised.
Two people remained in Dunedin Hospital yesterday.
The incident sparked a nationwide conversation about the safety and security of retail workers.
Union retail, finance and commerce secretary Tali Williams said the union surveyed members about their experience with abuse over the weekend, and the results sent a strong message.
The level of security guard presence differed from store to store, and some members felt guards were not rostered on at the times they were needed.
Williams said the union wanted Countdown management to sit down with it and work out what safe staffing levels would look like. One example was not having sole staff members on in any department, she said.
Staff also wanted senior management to have meetings in every store around the country to discuss safety measures specific to each site.
"Every worker wants to be heard on what goes on in their store, they want to sit down with the company and they want to be heard."
The union had also raised the issue of security around stores, like Countdown Dunedin Central, that had pharmacies within them.
"Pharmacies need more security coverage."
She believed Countdown was reasonably receptive and open to dialogue, and it would be responding over the coming days.
There had been some discussion following the stabbing about the use of body cameras on staff, which were being trialled at supermarkets in Australia.
"We just want to get all the basics sorted first before we start talking about body cameras or anything like that," Williams said yesterday.
As for Dunedin staff, those needing more time before returning to work had been given discretionary leave, she said.
