Teachers across Nottingham will be on-strike today over council plans to split the school year into five terms.
This is the second strike held by the National Union of Teachers (NUT) on this matter. Last month, 18 city council schools closed, while 33 others opened with a reduced timetable.
Around 20 schools are expected to close during the strikes today.
The council believes children fall out of the habit of learning during long breaks.
But the National Union of Teachers says it will make teaching harder.
The teachers believe the decision to change the number of school terms was made before a full consultation.
The main picket line will be at Ellis Guilford School and Sports College, which is expected to remain partly open.
The consultation is due to end on May 18th.
