General Motors' Australian subsidiary Holden has offered its 5,000 blue collar workers a 16.3 per cent rise to settle its long-running enterprise workplace agreement dispute, writes Mike Duffy. But the company has stressed the increase, spread over the next three years, is a 'bottom line' position. Workers will get an immediate 6 per cent increase, another 5 per cent next August and 4.5 per cent in 2003. This totals 15.5 per cent over the life of the agreement - or 16.3 per cent when the increases are compounded. The offer compares with the 15.25 per cent increase Ford Australia has agreed to pay its workers and 14.75 per cent rises for Mitsubishi's workforce.
