Nine to Five (1980)

Jane Fonda, Lily Tomlin and Dolly Parton give office hierarchy three different faces of exasperation. Their boss treats rank as permission to belittle people; the women's developing alliance makes his supposedly natural authority look wonderfully ridiculous. 9 to 5 earns the older benchmark slot through that shift from isolated grievance to comic solidarity. Its fantasies and escalating retaliation go well beyond everyday realism, but the jokes stay anchored in who gets credit, who makes the rules and whose work is taken for granted.
