Say what you will about France’s high schools, they still produce world-class slogan writers. Here’s a brief selection spotted during three weeks of blockades and marches over chronic teacher shortages, overcrowded classes and crumbling buildings:

“Pas d’avenir, pas de calme” (No future, no calm). “Diplômés aujourd’hui, précaires demain” (Graduates today, insecure tomorrow). “Vous détruisez notre futur, on bloque votre présent” (You destroy our future, we block your present).

More than 160,000 schoolchildren, students and trade unionists have marched in cities across France as protests over high school education continued into a third week and many demonstrators denounced policing tactics.

Riot police fired teargas at the end of Tuesday’s marches in Nantes and near the Montparnasse area of Paris, but most of the demonstrations over teacher shortages, overcrowded classes and crumbling school buildings held in cities including Lyon, Lille and Marseille were peaceful.
