The Amicus trade union has begun voting on plans to launch a strike at Nissan Motor Co. Ltd.’s Sunderland, U.K., plant, following Nissan’s snub of the union’s request for talks.

Amicus is protesting the mandatory relocation of purchasing staff from Sunderland to another Nissan site in Cranfield, Bedfordshire, U.K. The union says it never was consulted about the move, nor were the employees involved.

If approved, it would be Sunderland’s first-ever strike. Results of the voting are expected Dec. 8.

“The way that Nissan (has) treated (its) purchasing staff in refusing to even discuss with us their relocation is simply diabolical – we intend to fully back our members and call for the company to begin negotiations with us now,” an Amicus official tells Reuters.
