A branch worker said he was shocked by the number of people allowed to enter the store.
Police were called to the South Shields store and took no further action, but said they would “monitor the situation”.
A company spokesperson denied the existence of wrongdoing or a decline in social distancing – but a staff member who witnessed it said there were problems.
The worker told ChronicleLive, “I walked into the store and my first thought was,” Is the coronavirus then? “
“There was no queue outside and no one was standing at the door. It was a shop for everyone in the shop, it was like a zoo.
“I spoke to other staff and one told me that an NHS worker in the store was panicking to catch her because she had to go to work.
“Customers also complained to management.”
The staff member told ChronicleLive that, of the 30 to 40 workers on site, between 12 and 15 employees had left, although some returned later.
A spokesperson for Home Bargains management denied there were any failures: “All of our stores currently have social distancing procedures in place, including our South Shields store.
“Members of our management team visited the site today to ensure that all relevant procedures are followed and to reassure staff and customers after the concerns have been initially raised.
“We also spoke with the Northumbria police, who confirmed that they were satisfied with our social distancing provisions in stores.”
A Northumbria police spokesman confirmed that an officer had visited the store.
They said, “We can confirm that the police were called to the Home Bargains store at the Millbank Industrial Estate today (Monday) shortly after 11:00 am due to concerns about social distancing at the store.
“An agent visited the store and spoke to management. We are confident that social distancing measures remain in place in the store and we will monitor the situation. “
