The workforce at the Pirelli tyres factory in Cumbria, are waiting to hear when production will start again after their extended festive holiday.
Work was due to resume again on Thursday, but a leak in a high-pressure steam system at the plant in Carlisle has kept the Dalston Road factory closed.
The company, which set up the Cumbrian plant in 1969 and employs around 1,000 workers, is urgently reviewing the situation.
Workers at the plant, which makes car and SUV tyres according to the Pirelli website, were dealt a blow last November when the company reduced the working week as a result of the collapse in the global car sales market.
The extended Christmas and New Year shutdown was also in response to the reduction in world-wide demand for tyres.
The decision was taken after other measures, including scrapping overtime, failed to produce enough savings.
