The union for workers at Graeme Lowe Tannery says staff have been told a large contract with Silver Fern Farms will not be renewed.
The Hastings tannery is one of the biggest hide processing plants in the country and is owned by Lowe Corporation.
Lowe Corp has interests in other agri-business companies, property and farming around NZ.
The tannery's exact number of employees is unknown but in 2020 Graeme Lowe Tannery Limited applied for 80 employees to be paid under the initial Covid-19 wage subsidy, then 90 employees in the wage subsidy extension.
Local E tū organiser Ruth Sproston said the tannery workers' unions were told the news on January 27 before meetings with Lowe Corporation employees began.
