Which character was formerly a servant in the Proctor household and was fired after an affair?

The character who was formerly a servant in the Proctor household and was fired due to an affair is Abigail Williams. In Arthur Miller's "The Crucible," Abigail had an affair with John Proctor while she worked for him and his wife, Elizabeth. After Elizabeth discovered the affair, she dismissed Abigail from their service. This event significantly impacts the narrative, as Abigail's desire for Proctor and her subsequent actions lead to a series of tragic events in Salem, including the witch trials. Abigail's motivations are driven by her obsession with Proctor, which sets the stage for her role in the hysteria that ensues in the play.
