Tata Steel workers across the Britain will go on strike later this month in a row over British Steel pension scheme, British trade unions have announced.

The action would take place on June 22, while a ban on overtime and work-to-rule will be carried out next week, BBC reported.

The dispute was over proposed changes to pensions which could see employees retiring at 65 instead of 60.

Roy Rickhuss, general secretary of the Community trade union, said Tata had given workers “no option” but take industrial action.

On Monday, a television channel reported that Tata Steel Chairman Cyrus Mistry had written a letter to British Prime Minister David Cameron, softening the company’s stance in the dispute.
