Workers laid off at the clothing manufacturer Lane Walker Rudkin fear they may not receive even their final week's wages.
The company, which is in receivership, shed nearly 200 staff on Friday, offering no redundancy or holiday pay.
Beth Regnault, who has worked at the company's Greytown factory for 30 years, says she feels particularly devastated for colleagues with young families.
She says Lane Walker Rudkin's receivers are making no promises about whether they will get what they are entitled to.
Ms Regnault says it is not known whether there is money in the bank for staff to be paid for the work they did last week.
Meanwhile, the National Distribution Union, which represents the workers, is holding a fundraising stall outside Westpac House in Wellington on Monday.
National secretary, Laila Harre, says the union believes the bank is partially responsible for the job losses, and allowed the company to continue trading and building debt.
