Workers in Mansfield, Sunderland and Wakefield are at the highest risk of having their jobs taken by machines, according to a report warning that automation stands to further widen the north-south divide. From a report: Outside of the south of England, one in four jobs are at risk of being replaced by advances in technology -- much higher than the 18% average for wealthier locations closer to London. Struggling towns and cities in the north and the Midlands are most exposed. A total of 3.6m UK jobs could be replaced by machines. The Centre for Cities thinktank says almost one-third of the jobs in the Nottinghamshire town of Mansfield, near the Sports Direct warehouse, are involved in lines of work under threat as robots begin to replace humans in the years up to 2030. Jobs at the highest risk of replacement include those in retail sales, customer services, administration and warehouse work.
