The T&G union has forced pottery company Imerys to back down from unilaterally introducing worse pension arrangements for its workers.
Imerys, formerly English China Clay, is Cornwall’s largest private employer.
Managers had refused to negotiate over changes to their workers’ pension scheme that came into effect in January this year.
Under the threat of strike action the company has now agreed to fully consult with the unions over all future and retrospective pension proposals.
This includes the changes which had caused such anger among the workers.
These cuts would have seen 2,500 workers’ pensions downgraded by the equivalent of up to one third, and for some, by as much as 40 percent.
The company also closed the pension scheme to all new employees.
As well as T&G members voting for strike action, workers lobbied Imerys’ shareholders’ meeting in Paris with trade unionists from the US and France.
The T&G and other unions at Imerys will now discuss pensions changes with the company.
