While the strike will largely be attended by secondary school students, NZEI says it is aware that some primary students will attend with whānau.

"Today's children will be the ones who have to live with the consequences of adults' apathy and inaction over the past few decades.

"They're rightly angry, and it's about time politicians around the globe started thinking beyond the next electoral cycle," says NZEI president Lynda Stuart.  

Stuart says having an understanding of environmental, political and social issues is part of the curriculum.

"Some primary-aged children are passionate about these issues and plan to attend climate change rallies with their families this Friday.

"It will be important that they liaise with their school about attending.

"I know many schools will use Friday's action as a springboard for discussions about the environment and related issues."

Stuart joins more than 1200 New Zealand professors, researchers and educators in signing an open letter supporting young citizens taking strike action around the globe this Friday.
