The warehouse in Grimethorpe has nine confirmed cases of the virus among its staff.
The firm was given Barnsley Council’s approval to remain operational after inspectors visited the site. The Chronicle understands there is no evidence that the nine staff members - some of whom hadn’t been on site for more than two weeks before being tested positive - contracted the virus at the site.
In response to news of the virus cases, the trade union GMB is petitioning for more to be done to protect ASOS employees.
In a letter to the council, GMB organiser Will Dalton said: “ASOS is Barnsley’s largest employer, and also has a poor record of health and safety, but it has not been closed during this time and it is unbelievable to us.”
Coun Sir Steve Houghton, leader of Barnsley Council, said: “Our regulatory services team have been making regular unannounced visits to the site to ensure the safety of staff.
“The company has put various measures in place to protect staff, and has quickly taken on board and acted on all advice and suggestions to improve things further.”
