The civil service workers' union PCS will strike again, over severance terms, on 24 March.
Further strike action was announced at the rally in London on the second day of PCS's two-day strike on the issue on 8-9 March.
The initial announcement was a strike on 19 March, but we understand that the actual date is more likely to be Budget Day, 24 March.
The issue is Government plans to cut workers' entitlements to severance pay in case of redundancy. If the entitlements are cut, it will be cheaper and easier for the next Government, Tory or New Labour, to slash thousands of jobs from the civil service.
