Sources said that the financial woes bedevilling the company were ignited by a debt cancellation exercise, which saw the body write off $55m owed by farmers and local authorities in August last year.
The workers claim they had not been paid for several months and are calling on the government to pay them immediately.
The workers marched along the streets of Masvingo city before grouping at the offices of provincial affairs minster Kudakwashe Bhasikiti, where they handed over a petition.
Workers said that they were living in poverty while management was looting funds at their expense.
The workers also urged government to deal with what they called rampant corruption at the parastatal.
Bhasikiti this week confirmed that he had received a petition from the workers and was handling the matter.
Officials at Zinwa refused to comment, but Zinwa finance director Honest Murindagomo is on record saying that the debt cancellation initiated by president Robert Mugabe and Zanu (PF) had compounded the serious financial problems at the institution.
Like many parastatals in the country, Zinwa wrote off debts during the run-up to the July 31 elections. Robert Mugabe and his Zanu (PF) party used debt cancellation as a campaign tool.Post published in: News
