B1 Slang Informal

Bosser.

To work hard; to toil.

Meaning

Informal verb meaning to work, often implying hard or tedious work.

🌍

Cultural Background

The '35 heures' (35-hour work week) is a legal standard, but many professionals 'bossent' much more. Using 'bosser' often highlights the extra effort beyond the legal minimum. In Quebec, 'bosser' is understood but sounds very European. Quebecers are more likely to use 'travailler' or the anglicism 'jobber' for casual work. In Francophone Africa, 'bosser' is highly valued in the context of education. A 'bosseur' is a student who is respected for their dedication to their studies. The 'Start-up Nation' trend has popularized 'bosser' even in semi-formal meetings, as it sounds more dynamic and 'Americanized' in its energy.

Interview Danger
