Strikes are taking place across the UK in a series of disputes with the government over pay, pensions and cuts, with more than a million public sector workers expected to join the action.
Teachers, council staff, firefighters and civil servants are among those taking industrial action.
Unison general secretary Dave Prentis said workers were now £4,000 a year worse off than they were in 2010.
Prime Minister David Cameron has promised to tighten strike ballot laws
