GMB members at Pilkington Plyglass will down tools next week in a dispute over pay.
GMB union has announced two days of strike action at the glass manufacturer.
Workers at the firm produce specialist glass materials, including for the building of Dubai’s Palm Tower and the Stonehenge visitors’ centre.
The union says the strike comes after workers at the site “were offered real terms pay cut for a third year in a row.”
The company have been criticised for disparity in pay between Pilkington sites, with workers in Derbyshire reportedly offered a pay package £750 less than counterparts in other parts of the UK business.
Workers will strike on Wednesday 24 and Thursday 25 May.
Norma Kerr, GMB organiser, said: “GMB members at Pilkington Plyglass undertake essential and highly skilled work producing glass for iconic buildings across the world.
“This is a multi-national company, offering workers here in Derbyshire less than those a few miles up the road. Our members have been forced to the picket line to fight for the fair pay they so clearly deserve.
“If Pilkington top brass thought GMB members were going to accept this sitting down; those expectations are about to be shattered.”
