WORKERS at a nuclear power station have voted to go on strike in a dispute over pay, it has been announced.

Members of the Unite union at the Dounreay nuclear power plant, located on the north coast of Caithness in the Highlands, will strike over a pay dispute.

Two days of strikes planned for earlier this month were cancelled to allow talks, but workers have rejected the latest offer and will now walk out on Wednesday.

The offer from Nuclear Restoration Services (NRS) proposed a one-off £500 payment on top of a basic 4.5% increase.

Both GMB and Prospect unions have also been balloting their members on a walk-out.

Unite union members have also supported an overtime ban from Wednesday with a further day of industrial action planned for May 29.

The pay dispute involves most of the nuclear site's 1200 staff.

The plant is in the process of being decommissioned and workers are tasked with cleaning up the Caithness complex, which operated as a nuclear plant until 1994.

Dounreay was built in the 1950s and was Scotland's first operational nuclear reactor.

The UK Government has been approached for comment.
