Schools across England are facing widespread disruption today as teachers hold their second strike this week.
Members of the National Education Union (NEU) will be heading to the picket line after a similar walkout on Wednesday resulted in many schools closing entirely or being forced to reduce the number of classes held.
It comes amid a long-running dispute over pay, with union leaders warning strikes could continue into the autumn unless a deal can be reached.
The timing of the strike action has been criticised by some as it is set to disrupt end-of-year activities - including trips, sports days and transition days for pupils heading to new schools.
But the NEU said ministers could have easily ended the disruption by offering a better pay deal to help teachers amid high inflation and the cost of living crisis.
Friday marks the eighth day individual schools in England have faced walkouts by NEU members since February.
The government previously offered a £1,000 one-off payment to teachers and an average 4.5% rise for staff in the next school year.
