Teachers at all state-funded schools in Barnet will strike in February and March over pay and school fundings.
The National Education Union (NEU) told the Times that strikes are expected to take place on February 1 and 2 as well as March 15 and 16 in Barnet.
Members will also protest in Westminster over pay and the need for proper funding.

A spokesperson for the NEU in Barnet said: “On February 1, Barnet NEU members will head to Central London to march past Downing Street to Westminster to demonstrate that schools need proper funding.
“The Government has to address the erosion of teachers' pay since 2010 which has resulted in teachers leaving the profession in vast numbers.
“This has resulted in dreadful situations like children being taught chemistry and physics from textbooks by non-specialists,” he added.
Nine out of ten members of the NEU in England voted in favour of the action with a turnout of 53.27% passing the threshold of 50% required by law.
More than 23,000 schools across England and Wales are expected to be affected for up to four days out of the seven days of strike announced by the union.
A Department for Education spokesperson said: “Education Secretary Gillian Keegan held a further meeting with union leaders this morning, listening to their concerns and engaging in a constructive discussion around a broad range of issues.
“She reiterated that strike action would be highly damaging to children's education, particularly following the disruption experienced over the past two years.
“Discussions will continue this week, ahead of the planned strike action.”
