Workers at The Pensions Regulator (TPR) are set for further strike action for 14 days over a dispute in pay.
Over 280 members of the Public and Commercial Services union (PCS) walk out on 11, 12, 17, 18, 23-27, 30 October, and 31 then again on 1 to 3 November.
The PCS union have accused the TPR of refusing to provide workers with the government recommended pay offer of 4.5% to 5%.
PCS general secretary Mark Serwotka said,: “TPR management’s disgraceful decision to give their staff less than anyone else has served only to backfire on them by making our members more determined than ever to secure a fair pay rise.
“Following their strike action earlier this month, they are returning to the picket line in the expectation their managers will listen to them or face the possibility of even more strikes in the future.”
