This does not read like an "effort to oppose phonics education". In fact, I did not see one mention of one single teacher who is opposed to phonics.
The complaints are about implementation timelines, continuing education requirements, potential over-stepping of policy-makers re: teacher autonomy in the classroom, etc.
>“To the extent that these laws remove teacher choice from certain decisions about curriculum and pedagogy and instructional style, it’s not at all a surprise that you’d see unions be in opposition to those, even if they support the arguments behind the science of reading,” said Melissa Arnold Lyon, an assistant professor of public policy at the University at Albany.
>"“That’s establishing a precedent that is really dangerous and really could open up schools and teachers to all kinds of litigation, and all kinds of conflict and problems,” said Scott DiMauro, the president of the Ohio Education Association. “You’ve got to always be cautious about micromanaging decisions that ought to be made at the local level.”"
>“That raises a lot of academic freedom questions for us, that raises a lot of questions about being able to differentiate based on student need,” said Justin Killian, an education issues specialist at Education Minnesota."
>District leaders need time to create new instructional plans, money for new curriculum materials, and systems in place for coaching and supporting teachers—provisions these laws don’t always include, Woulfin said.
You are confusing "against the legislation as it is written" with "against teaching phonics".
