Without recourse, Dang and Son relocated to Hanoi where, for the last three years, they have been working as trash collectors for Minh Quan Hi-tech JSC.
But since the firm has delayed salary payments for the past seven months, the couple has been plunged into a precarious situation.
"I've been working for the company without a contract for a long time. I only officially signed one in 2017. Recently, my health has grown worse, and combined with the fact that salaries have been delayed, I've been staying home full-time. Both my wife and daughter-in-law, who work the same job, have had their salaries delayed for six-seven months," said Dang.
