Which Hesiod poem describes Pandora as part of the origin of human suffering?

Works and Days describes Pandora as part of the origin of human suffering.

Hesiod’s Works and Days is a didactic poem that combines advice about farming and seasonal work with stories about justice, labor, and the condition of humanity. Its Pandora narrative explains how evils entered the human world after Zeus responded to Prometheus’s theft of fire.

The poem describes the gods creating and adorning Pandora, then connects her with a jar whose contents escape. Hope remains inside after the evils depart. This version is the principal source for the familiar story, even though later retellings frequently simplify or alter it.

Theogony also refers to Pandora and her creation, but Works and Days provides the fuller sequence involving Epimetheus, the vessel, and the released troubles. The Iliad and Odyssey are Homeric epics, not the main ancient source for this myth.
