The Australian Greens say the ACTU is selling out workers by not arguing more strongly for industrial relations changes and by settling for a meagre jobs tally under the Government's failed Carbon Pollution Reduction Scheme.

Greens Leader Senator Bob Brown said he was disappointed ACTU President Sharan Burrow was not pushing the Federal Government more strongly to create jobs and to protect workers entitlements.

While the G20 meeting ended up in raptures about the future of growth economics, it turned its back on the plight of planet Earth's environment, Australian Greens Leader Bob Brown said today.

"The G20 found more than a trillion dollars to address the economic crisis but no money to address the environmental crisis," Senator Brown said.

Senator Brown and Senator Rachel Siewert will meet with Deputy Prime Minister Julia Gillard later this afternoon to discuss the Fair Work Bill.

Amongst others, the key amendments the Greens will be proposing are:

The showdown over greedy CEO payouts is a test of the Rudd government's Labor credentials, Australian Greens Leader Bob Brown said today.

"The CEO's CEO, John Colvin, (pg 1, Sydney Morning Herald) used exactly the same terminology - ‘perverse effects' - used by Finance Minister Lindsay Tanner on the weekend to warn against empowering shareholders," Senator Brown said.

"The government and corporate bosses are singing from the same song sheet. It's time Labor put Australian shareholders first," Senator Brown said.
