Car parts supplier Autodom has reopened its doors in Melbourne after being placed into receivership yesterday.
The union has addressed workers at Autodom's Dandenong South factory for the first time since they were stood down last week.
Four hundred workers from South Australia and Victoria face an uncertain future while receiver McGrathNichol examines the firm's ongoing viability.
An industry-led guarantee of Autodom's debt has ensured parts supplies for the major car makers and workers jobs for now.
The receivers say the company is now being prepared for sale.
It supplies bumper bars and brake parts to the big car makers.
The 200 workers at subsidiary Dair in Dandenong South and Gisborne have been told to report for work today.
Assistant state secretary of the Australian Manufacturing Workers Union (AMWU) Leigh Diehm says workers are concerned about their future.
"There's a hell of a lot on the line," he said.
"We've got families, mums and dads that both work out here, so their whole wage comes from this particular site and the other two sites across Australia." Some aiAutomotive employees in Adelaide were called back to work yesterday with the rest of the workforce to resume work today.
