Do You Know Sunday-Monday? (1969)

Juli is a 17-year-old student who takes a summer job in a local chemical factory. She is befriended by Piri, a girl with an unsavory reputation who has worked there before. The two friends are ogled by male workers who have overactive libidos and imaginations. Juli spurns the advances of a deluded Romeo while Piri continues to work and endure open hostility from the older female workers while her slothful parents sink deeper into alcoholism.
