Talks to help Holden long-term: Weatherill NEGOTIATIONS to provide ongoing aid to car maker Holden are not designed to just give the company a stay of execution, South Australian Premier Jay Weatherill says. Mr Weatherill says the SA government, the Commonwealth and unions are deeply involved in discussions. But he declined to respond directly to reports that the company is set to get another $200 million from the federal government, on top of the $275 million package negotiated last year to keep the company going until at least 2022. Holden has also declined to comment on the new figure. "We are not just trying to give Holden a stay of execution," Mr Weatherill told reporters on Monday. The objective is to secure a future for Holden. Mr Weatherill said the negotiations with the Commonwealth would also seek to overcome problems presented by recent changes to the fringe benefits tax (FBT) on company cars which the car industry says will impact demand. The Federal Chamber of Automotive Industries (FCAI) believes the changes will cut total car sales by 10 per cent and slash demand for locally-made cars by 20 per cent. Opposition industry spokeswoman Sophie Mirabella said the FCAI analysis confirmed the federal government's misjudgment in its "catastrophic change of policy." Shadow Treasurer Joe Hockey said the government's changes had done more damage to the auto industry than could be undone with another injection of taxpayer funds. South Australia remains at odds with the Commonwealth on the tax changes and has put a number of measures to the government for it to consider. Mr Weatherill said the overall outcome would need to present "no barrier to Holden agreeing to the co-investment program." As well as seeking extra government funds Holden has told its workers it needs to cut labour costs and they will be asked to vote on a range of measures next month. Unions have agreed to forgo an upcoming pay increase but say pay cuts will not be supported. Last week about 400 Holden workers in Adelaide left the company after agreeing to take voluntary redundancy, cutting the company's SA workforce to 1700.
