A further 33,000 more civil servants have voted to strike next month – joining 100,000 already walking out.
The newly balloted members of the Public and Commercial Services (PCS) union will join the other civil servants who are walking out on 15 March.
They are calling for a pay rise of at least 10%, changes to pensions, job security and no cuts to redundancy pay.
Ten groups of civil servants, previously balloted along with the others in November, failed to reach the 50% turnout threshold but in a re-ballot, which ended yesterday, all of them reached the threshold and voted to strike.
The new groups who are joining the day of action include: the Care Commission, Companies House, HMRC, the Information Commissioner’s Office, the National Museum of Wales, Office of Rail & Road, UK Export Finance, UK SBS, the Valuation Office Agency and the Welsh Government.
