Up to 90 jobs are at risk at a Scots manufacturing firm after bus company Alexander Dennis revealed plans to pull out of Scotland. Workers at Greenfold Systems Ltd in Dunfermline were informed of potential redundancies as around half the workforce are employed to construct parts for the firm’s buses. The building – one of three – is dedicated to the work on the buses, with other sites in Lochgelly and Chatham, England. Graeme Downie, Labour MP for Dunfermline and Dollar , said he has written to First Minister John Swinney about the threat of job losses. He told STV News: 鈥淭he management and staff at Greenfold Systems are doing their best in an incredibly difficult situation but the fact these 90 jobs in Dunfermline are at risk just shows the ripple effects of the SNP鈥檚 economic incompetence and their failure to support Alexander Dennis and bus building in Scotland.鈥 Plans under consultation at Alexander Dennis would close their Falkirk plant and cease production at the nearby Larbert factory, with 400 jobs at risk. Bosses at the bus firm this week said the closure of sites at Scotland is 鈥渘ot a done deal鈥. The company told MSPs that orders for up to 100 buses and changes to regulation are needed before the end of the year. The jobs would instead be consolidated at a single site in Scarborough. In evidence to a Holyrood committee, president and managing director Paul Davies said: 鈥淚t鈥檚 absolutely not a done deal, it is a consultation process.” Davies told the committee the firm would need to see consistent orders to help stabilise the future of the business in Scotland. He said this would be around 70 to 100 buses by the end of the year and 300 to 400 for next year. Calls have been made for a furlough scheme to be put in place, with the Government being urged to step in and pay workers until building can begin. Deputy First Minister Kate Forbes pledged earlier this month to 鈥渓eave no stone unturned鈥 to secure a future for the workers at risk. Scottish Liberal Democrat economy spokesperson Jamie Greene MSP said: 鈥淭his will be an extremely difficult time for the workforce at Greenfold Systems, and my thoughts are with them today. 鈥淭he SNP鈥檚 failure to support bus building and buying in Scotland is inflicting a chain reaction of misery for workers and local communities across the country. 鈥淚f the SNP government are serious about delivering for our economy, they should be sitting down with the firm to thrash out a solution and finally get behind Scottish manufacturing.鈥 Minister for Business and Employment Richard Lochhead said: 鈥淚 am very disappointed to learn that Greenfold Systems Ltd has entered into consultation with a view to making redundancies at its Dunfermline site. 鈥淭his will be a difficult time for the employees at risk of losing their jobs, their families and for the local area. Scottish Enterprise will engage with the company to better understand the reasons for this decision and whether it can offer any assistance. 鈥淭he people affected by this announcement are our immediate priority and the Scottish Government will do everything in its power to help those affected through our initiative for responding to potential redundancy situations, Partnership Action for Continuing Employment.鈥 Greenfold Systems Ltd has been contacted for comment.
