ENTERPRISE Agreement negotiations at Wetherill Park's Ausreo is still continuing, with union members standing their ground.
Nearly 30 of the company's workers are still on strike, with the Australian Council of Trade Unions (ACTU) president Ged Kearney joining them at the picket line last week.
Ms Kearney said the workers were seeking a $3 per hour pay rise, which would put them on par with workers in Ausreo's Melbourne factory.
"The Victorian workers do the same work but they have higher wages, better conditions and a better redundancy agreement," she said.
"This is particularly unfair when you consider the higher cost of living in Sydney.
"I am here today to urge Ausreo to be fair and give these workers the pay rise they are entitled to."
But the company's management team, via a statement to the Champion, said the company did not meet with Ms Kearney last week to discuss wage increases.
Instead, they said they met with the Australian Manufacturing Workers' Union (AMWU) NSW branch assistant state secretary Steve Murphy who acknowledged that: "Ausreo was in fact paying its workers between 10 and 30 per cent more than its like-sized competitors in Sydney".
"The AMWU members' claim for a $3 per hour wage increase represents a 12 per cent annual increase which is neither workable nor sustainable in the current competitive building and construction environment," the Ausreo management team stated.
"Ausreo has been in discussion with the AMWU for the past five months and has offered its factory employees a guaranteed annual payment of three per cent over three years, which has been rejected."
