The National Education Union (NEU) said that 23,400 schools in England and Wales would be affected today (Tuesday) as it was estimated 200,000 workers walked out. Strike action was also taken by university staff, rail workers and NHS staff in what is thought to be the biggest day of action in over a decade.
In Leeds, crowds were entertained by the Commoners Choir led by Chumbawamba guitarist Boff Whalley, before moving off for a march down The Headrow. Unions represented in the crowd included the PCU, RMT, NEU, Unison, UCU and the GMB.
Below are 10 pictures from the day of action.
