Workers at a Teesside chemical plant have come out in favour of industrial action over a threat to 120 jobs.
Bosses at Eaglescliffe-based Elementis Chromium say cuts are needed as part of a restructuring process at the site.
But unions claim jobs losses are unnecessary and the long-term future of the 320-workforce plant is viable.
More than 80% of union members belonging to the Transport and General Workers Union have voted in favour of industrial action.
Union officials at the plant say the 86% vote for action was a "clear indication" of the level of frustration at the plant.
Union organiser Joe Keith said: "The overwhelming support shows our members are not prepared to sit back, they will fight back."
"This result shows there is deep anger at the plans for job cuts."
The union has blamed finance company Hanover, which owns 15% of Elementis Chromium, for trying to force through job cuts.
It has also expressed concern at the long-term security of the company's pension fund.
