|| CMC Motors assembles specialist motor vehicles such as Lorries, buses and trucks. The company owns four assembly plants to which parts are delivered and assembled into the motor vehicles. The motor vehicles are assembled using a mix of robot and manual production lines. The 'human' workers normally work a standard eight hour day, although this is supplemented by overtime on a regular basis as the company has a full order book. There is one shift per day; mass production and around the clock working are not possible due to the specialist nature of the motor vehicles being assembled. Wages system - shift workers Shift-workers arrive for work at about 7.00 am and 'clock in' using an electronic identification card. The card is scanned by the time recording system and each production shift-worker's identification number is read from their card by the scanner. The worker is then logged in as being at work. Shift-workers are paid from the time of logging in. The logging in process is not monitored as it is assumed that shift-workers would not work without first logging in on the time recording system.Shift-workers are split into groups of about 25 employees, with each group under the supervision of a shift foreman. Each day, each group of shiftworkers is allocated a specific vehicle to manufacture. At least 400 vehicles have to be manufactured each day by each work group. If necessary, overtime is worked to complete the day's quota of vehicles. The shift foremanis not required to monitor the extent of any overtime working although the foreman does ensure workers are not taking unnecessary or prolonged breaks which would automatically increase the amount of overtime worked. Shift-workers log off at the end of each shift by re-scanning their identification card.
