The Comedy of Work (1988)

Original title: La comédie du travail

Sylvain Berg, a "professional" unemployed who spends his time hiking and mountain climbing, and "model" bank employee Benoît Constant, who has just been fired and does not want his wife to find out, both find themselves in Françoise Duru's office at an employment agency. Françoise is secretly in love with Sylvain, so in order to keep him close she convinces her employer to give Sylvain a job he doesn't want, instead of Benoit who not only wants it but also has the right qualifications.
