Production at Hyundai Motor's Genesis luxury car line in Ulsan has been halted for a second day on Tuesday, due to a deadlock between labor and management over staffing requirements for new models. According to industry sources, the Genesis production line at Hyundai Motor's Plant 5 in Ulsan, southeastern South Korea, remained idle on Tuesday after closing on Monday, with production, which typically starts at 6:45 AM, yet to resume.
