Teachers are on strike today meaning many of the borough's schools have been forced to shut either partially or completely.
Members of the National Teachers Union (NUT) are on strike in a dispute over Education Secretary Michael Gove's reforms that affect pay, workload and pensions.
Striking teachers from Sutton outside Broadcasting House in London
Many teachers from Sutton are taking part in a march in central London to show their disapproval.
Most of the borough's schools are affected with some, including Stanley Park High School, closing completely during the walkout.
Other schools are running limited lessons although some, including Cheam High School and Glenthorne, are unaffected.
Andy Gibbons, Sutton secretary of the NUT, said: "Teacher workload is unsustainable and the thought of doing the job until 68 is driving many away from the job.
"Teacher morale is at dangerously low levels. Children need teachers who are fresh and well motivated not tired and demoralised.
"All the polls show that Michael Gove is out of touch with teachers and parents – he must listen and change direction.
"This strike is his fault - teachers do not like taking strike action but they are prepared to lose pay to stand up for education.
"We do apologise for the inconvenience to parents but we hope they will support us."
Members from Sutton have joined other London teachers in Marching from Broadcasting House to Downing Street via Regent Street and Piccadilly Circus before taking part in a rally in Westminster.
Many of the schools affected are running special classes for children preparing for exams but parents across the borough have found themselves having to make arrangements for their children.
The Department for Education has criticised the striking teachers and said parents "will struggle to understand" their reasons.
