Deputy Prime Minister Barnaby Joyce has been asked to join the fight to get sacked Appin miner Dave McLachlan his job back.
Mr McLachlan was terminated by South32 last month, following an undies protest in March.
His dismissal has sparked a national CFMEU-led campaign.
Illawarra Labor MPs Sharon Bird (Cunningham) and Stephen Jones (Whitlam) have thrown their support behind the fight – and want Mr Joyce to do the same.
In a joint statement, the MPs said Mr Joyce was the “self-proclaimed best friend of the miners” and should work with South32 to get Mr McLachlan reinstated.
The call comes after Mr Jones showed a copy of the Mercury’s May 5 front page in the Parliament last week.
Appin miners wore their underwear for 10 minutes on March 7, to highlight issues with South32’s supply of work clothes and a delay of more than a year in providing a promised laundry service.
