How old are you?
I'm the same age as many grandmothers (born in 56) but still teaching (a head).
Phonics works. We don't need to qualify a sentence such as that with 'in most cases'. Phonics works as a method of decoding the vast majority of English words. Considering it's such a mongrel language, that's pretty impressive.
Some words are classed as 'undecodable' but these are few and far between. It's better to learn these exceptions individually.
There are a few children who simply can't get phonics. These children tend to have their own issues or abilities.
I'd be delighted to discuss literacy in education, semantics or modal logic / discrete mathematics. All of which I would stake my house on being better read in than you. We're only discussing the first so stop trying to score cheap points against @steppemum.
Look / say has its benefits. I don't think any teacher should be devoted to one method. However, having spent 2 decades programming computers to recognise spoken language (largely phonics based), nothing will dissuade me from the benefits of phonics. It fits most words for most children. 15% of a class not 'getting' phonics sounds like an anomaly or simply that it was poorly taught.
Look / say works for tricky, non-decodable words. It's an inefficient way of learning to read but there's an argument that children teach themselves phonetic rules from look / say. This is a slower and less beneficial route though.
You're yet to answer how you could read an unseen word or nonsense word.
