I have read article like that in the past, but my google skills are failing me. I keep finding articles about a french teacher who drank wine with his 14 year old students, another fired for racist, the first lady of France, and other reason for firing teachers.
The closest I can find at the moment is
https://www.thelocal.fr/20160830/ten-ways-to-fix-the-french-school-systemThe national education system is huge and highly centralized. With more than 1 million personnel, it's now bigger than the Russian Armed Forces—and it's run a bit like an army, in a rigid hierarchical manner that relies on command and control. Teachers are the grunts in the trenches who carry out orders, rather than respected professionals who are able to use their discretion and judgment. The curriculum, the timetable, the school hours, the allocation of finance and other resources and the decisions about which teachers should work in which schools are all decided by bureaucrats from the central authority, with the Minister of Education at its head.
Already from the age of eight, children spend hours of class time struggling to identify grammatical and linguistic structures, which they then must learn to call by the correct technical name. (In the classroom, this is known as learning the "nature and function of words"). That's all well and good for those who want to go on to study linguistics in later life, but it's horribly tedious and repetitive for most, and, at worst, can put them off reading for life.

All hiring and firing decisions made from a central authority, teachers having no say in what or how they teach - that's France for you.
