The Doncaster Star reports that another of Doncaster's oldest flagship manufacturing firms is under threat. Glass giant Pilkington (an employer in Doncaster for decades), has put its Kirk Sandall factory under review, putting a question mark over the jobs of its staff. Head of corporate affairs David Roycroft said: "As far as Kirk Sandall is concerned, it's certainly true that operations are under review."The way trading conditions are at the moment is quite difficult, so we are looking at the business, but there are no immediate plans to close the site." It comes as Kirk Sandall residents have been speculating that the factory could be closed. Doncaster Councillor Edwin Simpson told a meeting of Doncaster Council's planning committee: "I understand from residents that Pilkington plans to close in a year."
