"But we feel that strongly about it, and we've tried all the proper channels, and feel that this is the only option we've got left.''
The proposed closures and mergers affect hundreds of children at schools across Christchurch.
The biggest changes have been earmarked for the schools across the quake-affected eastern suburbs.
The NZEI has made a formal request to the Ministry of Education to put the decisions on hold and to launch "some proper consultation'' but it's fallen on deaf ears, Mrs Spekreijse said.
She said parents, and the wider community, are backing the action, especially given the key role schools played in providing children much-needed stability after the devastating earthquakes.
"We fail to see the big picture from the ministry in terms of education for Canterbury,'' says Mrs Spekreijse.
"The process hasn't been fair and robust. It shouldn't be a five-minute decision, it shouldn't be a Band-Aid. It's something we really need to consider.
"We want our children to stay here and have an amazing future in our rebuilt city.''
