Unison is conducting a ballot that could see 1.1 million workers strike on 30 November – and possibly beyond. The strike is over the Government’s public sector pension reforms. It affects works in local government and health service retirement schemes.

Other large public sector and civil service unions are already in the process of balloting, which could see over two million workers out, making it the biggest strike in UK history.

Dave Prentis, the general secretary of Unison said the strike “could take the form of targeted action against certain local authorities, health trusts or privatised service employers or the form of rolling action in certain regions.”
