FAMILIES face chaos this week as up to 4.5MILLION pupils look set to be sent home thanks to disruptive teachers' strikes.
Over 23,000 schools will be affected on Wednesday in the biggest day of industrial action for a decade - with many shutting alltogether.
It comes as members of the National Education Union (NEU) in England and Wales demand above-inflation pay rises.
Figures suggest that up to 150,000 teachers could be out on strike that day.
90 per cent of the NEU's 300,000 members voted for Wednesday's walkout, turnout was 53 per cent.
Most schools impacted will be completely shut as its unsafe for kids if a school is understaffed, The Times reports.
