Rover, whose sales soared by 50% last month, is already in dispute with its production workers, who turned down a 2.5% pay rise last month because the proposed deal retained the unpopular 'banked hours' system. These are hours for which employees are paid and take off during slowdowns in production. They then work these hours for no more money when production speeds up again. This month, Rover stood down 1,000 workers for a day because it ran short of gearboxes made by the firm's former owner, BMW.
