Unions are ambivalent: they generally oppose the statutory “suspension” of the employment contract, a situation worse than a dismissal, but they can also be for the mass vaccination and not oppose to the discrimination of unvaccinated people.
Example with the Sud education union:
“SUD Education has been making demands for the health of staff and students since the start of the health crisis, and in particular for the rapid implementation of a massive vaccination campaign: the scientific community unanimously indicates that this is the only way out of the pandemic. […] As such, the implementation of a vaccination campaign in schools makes sense. […] The health pass is not implemented in schools and establishments. The health protocol published at the end of July, however, introduces the principle of the exclusion of only non-vaccinated contact cases. […] Even if we do not have any details on this subject, it would not be acceptable for National Education personnel to be required to take charge of the missions which would be linked to this measure. “

In other words, the South Education union does not oppose that the unvaccinated be expelled from schools, but it does not want to do it itself. Maybe policemen with dogs?
In addition, Sud Education identifies the movement against the health pass to the far right, and dissociates itself from it. “For vaccination, against the extreme right” headlines the union. Vaccination then becomes a political marker, an imaginary way to fight against the far right: against fear of progress, against conspiracy and obscurantism, against racism and anti-Semitism, against homophobia and military dictatorship! Why hadn’t we thought about it before? It was enough to be vaccinated to bring down Hitler!
