The Detroit Free Press is reporting that the GM Technical Center in Warren, Michigan has been shut down for cleaning after an employee tested positive for coronavirus.

The company found Monday that an employee of the Cole Engineering Center tested positive for the virus. As a response, GM cut employee card readers to the facility mid-day Monday and began an extensive cleaning of the facility and the employee’s work area.

GM expects the building to re-open later today but has told any workers who can complete their job remotely to do so. Employees who had contact with the infected worker have been notified and are being asked to self quarantine for 14 days.

A local union leader at the Romulus Engine plant has told the Free Press off the record that GM is cleaning for 30 minutes between each shift at the assembly line.

Like all automakers, GM has instructed employees to work from home if possible and banned all travel and group functions until further notice.
