The Communications, Electrical and Plumbing Union (CEPU) is awaiting word from Telstra on a claim for a $5-an-hour Olympic allowance, with just a few weeks to go until the Games begin.
CEPU president Laurie Chalker said: "Telstra was supposed to get back to us [mid August], and it hasn't."
Chalker said 1200 workers would be directly affected by the claim.
"Telstra is the only communications provider and the main sponsor, unlike the Atlanta games where there were several communications providers. Therefore, there is a lot of pressure for employees to be available and on time for work."
"We first approached Telstra with this claim a while ago, but got serious about it 10 months ago. Telstra is very good at fobbing things off and they are quite anti-union," Chalker said.
A Telstra spokesperson said the "claim is under consideration".
The spokesperson said, "CEPU only put out a press release about it two weeks ago", and that "to their knowledge" there had been no date set for a response to the CEPU's claim.
It has also been reported that the NSW Labor Council had been asked to assist the CEPU with their negotiations with Telstra but the Labor Council said it was not involved with the negotiations.
