Tristar: pictures at the gallery

The Australian Manufacturing Workers Union has stepped up a campaign to embarrass an Adelaide businessman locked in a bitter industrial dispute with Sydney workers.

Outside the South Australian Art Gallery, the AMWU displayed pictures of 29 TriStar staff embroiled in a fight over redundancy entitlements.

Andrew Gwinnett, chairman of TriStar's parent company Arrowcrest, is on the art gallery's board.

AMWU official Tim Ayres said the company had cut 90 per cent of its workforce. Those remaining had an average of 31 years' service.

If Tristar held out until next year, these workers would get a maximum 12 weeks' payout instead of four weeks for every year.
