The strike will see numerous civil service-run offices in Dundee and across the wider region closed for the day, including the main JobCentre in Gellatly Street and HM Revenue and Customs office in Greenmarket.

Next month’s stoppage is not related to the recent walkout’s by council employees in Tayside — represented by the Unison, Unite and GMB unions — who are also in dispute over their pay.

PCS Scotland East branch secretary Hamish Drummond said members did not want to cause inconvenience for the public, but action had to be taken over the current pay award.

He said experienced workers who had risen to the top of their pay bands were only being offered a 2% rise this year, followed by a 1% increase in the following 12 months.

Mr Drummond said the government’s “public sector pay restraint policy” had led to the unrest and the ballot for nationwide action.

He said, “If you keep it to this side of the Tay then you are looking at about 2000 union members striking between Perth and Arbroath. If you spread that further into Fife then you are looking at around 3000.

“The public-facing offices in terms of the HM Revenue and Customs delivery centre and the job centres will be closed. Any attempt to open them would only be done by bringing in management from outside the area.

“We regret any negative impact on the public, but without proper competitive pay for the civil servants working there these services are going to be sub-standard in the long-term.”
