In Paris, near the Luxembourg Gardens, the teachers met to “express their fed up” and demonstrate against the health protocol imposed by the government.
Thursday's mobilization is considered "historic" for the unions.
75% of primary school teachers went on strike, and nearly one in two schools was closed, according to figures from Snuipp-FSE.
A figure disputed by the Ministry of National Education, which only counted 40% of striking teachers.

The teachers and parents of students present expressed their anger at the "non-management" of the epidemic by the National Education.
They mainly demand that the rules be clear, that more staff be recruited, that more masks be distributed and that the classes close if a case of Covid-19 is declared there.
