Calsonic Kansei appointed NRG as its recruitment partner in 2013 to provide staff for production, the shop floor and warehouse, and fork lift trucks across its Washington and Sunderland sites.
The company's manufacturing operation relies on a flexible workforce of up to 20 per cent to work alongside its permanent employees.
NRG’s on-site team works in partnership with Calsonic to ensure that operational business objectives and targets are achieved through the provision of required staffing skills and volumes. After a competitive tender, the pair have renewed their agreement for another three years.
John Barnett, operations director of Calsonic Kansei, said: "The agency temporary workforce is integral in the operational efficiency for Calsonic Kansei, and we consider them part of our team.
"We are delighted to work in partnership with NRG as our chosen staffing partner. They are integrated with Calsonic teams and fully understand the operational best practice, efficiency and value we require to deliver total delivered cost savings to our customers."
Therese Liddle, chief executive of NRG, added: "The success of this contract is the relationship between the two businesses built on transparency, trust and confidence.
"We fully understand the complexity and challenges of Calsonic Kansei's operating model within the automotive sector and our recruitment expertise supports that need for excellence, flexibility, high quality and good value."
