Teachers' strikes could run into the summer term if ministers refuse to budge over pay, the UK's largest education union has warned.
National Education Union (NEU) bosses said they believe parents understand why teachers are preparing for walkouts and warned that strikes could run for months if the Government won't offer a decent pay rise for staff.
Millions of pupils are expected to be impacted by the NEU's first day of strike action on Wednesday, which will affect more than 23,000 schools in England and Wales.
