Être sur la brèche

Meaning: Being actively engaged in battle or difficult work.

Literally: To be on the breach

Example: “Pendant les soldes, les vendeurs sont sur la brèche du matin au soir.” — During the sales, the salespeople are on the go from morning to night.

English equivalent: To be in the thick of it

Origin: A brèche is the breach that siege guns open in a fortress wall, and it was where the fiercest fighting took place: attackers stormed it and defenders had to hold it at any cost. The Académie française's 1762 dictionary already has mourir sur la brèche (to die on the breach). Being sur la brèche came to mean being in the thick of the action, and then, more generally, working flat out without a break; George Sand used it in 1871.
