The strain is starting to show for hundreds of Gujarat NRE workers caught up in the Illawarra miner's financial woes.
Workers have not been paid since September 18, with the company missing their most recent pay day, Wednesday.
The CFMEU, which has 350 members across the company's Russell Vale and Wongawilli mines, recently extended financial support to a worker so he could buy insulin for a family member. Other workers with large families have also approached the union for financial assistance.
On Thursday and Friday, most workers arrived at the company's collieries and - told the situation was unchanged - went home without clocking on.
One worker, who did not want to be named, said up to 80 per cent of colleagues had gone home without working on Thursday and Friday.
Weekend workers at Russell Vale dropped an equivalent amount of hours in solidarity; weekend workers at Wongawilli completed their shifts, "for personal reasons".
"A few have been working because they have too many debts to take the risk," the worker said.
Some had left jobs at other mines to work for Gujarat.
The wages of some workers have dropped significantly since Christmas, when the company began scaling back to a "bare bones" 35-hour roster.
Union representatives will attempt to advance the workers' cause at a meeting with company management this morning.
