If they fail to respond, Oxfam publishes reports that aim to "name and shame" shonky companies and in some cases put pressure on investors to withdraw their support…[She] says Oxfam Australia has repeatedly lobbied the Federal Government to establish an independent complaints mechanism with real powers.
