Pirelli UK will restart production in Carlisle and Burton upon Trent from May 18 at a reduced rate.
Production was temporarily stopped on March 23 due to COVID-19, and Pirelli has put health and safety measures in place to protect employees returning to work.
Only a small number of employees will be needed to meet current production levels while staff in other areas such as commercial and administrative functions will be encouraged to work from home.
Safety measures will include temperature screening for everyone entering sites, compulsory PPE, physical distancing, restricted numbers in communal areas, and cleaning and sanitizing work areas several times a day.
