Thousands of council workers, teachers and firefighters from across the region have joined a day of action over pay, pensions and working conditions.
Libraries, museums and more than seven hundred schools have been closed or disrupted.
Unions claimed solid support for the strike but the government attacked them, arguing they are based on ballots with a low turnout.
Michael Billington reports:
Almost 600 schools have been closed across the region as teachers join a public sector strike.
