Q: Iris is a shy young professional who doesn't want to rock the boat at the office where she temps. Margaret is the polar opposite, and serves as a catalyst to help Iris become more assertive. Paula eagerly awaits post-work happy hours and the chance to flirt with attractive men. Jane (Ubach) is engaged to marry a jerk who is already cheating on her. Margaret hopes to become a permanent employee as an assistant to Mr. Lasky, but her dreams are thwarted when he suddenly dies. The four temps form a camaraderie which assists them in getting through their boring and tedious days at work. A series of thefts occur in the office and suspicion falls on the temps, particularly Margaret. When Iris finds a plastic monkey inside Margaret's desk that she had thought was stolen, Iris loses faith in Margaret and believes that she is the office thief. Margaret suggests a one-day strike from work due to mistreatment and being under appreciated as temps, and her friends halfheartedly agree to join her, but on the appointed day Margaret is the only one who does not come to work. As a result, the company's officious head of human resources fires Margaret, and management micromanages the remaining three temps. Iris, Paula and Jane's friendship comes to an end as result of the stress, ending the camaraderie among the temporary workers, and eventually they all go their separate ways. Paula is upset when she learns of Jane's wedding from a newspaper announcement, to which she was not invited, and leaves to work in another department. It is later discovered that another employee (a rich girl who was hired as a permanent employee after her first day) was the thief and that Margaret simply had a similar toy in her desk. Iris confronts the thief when her diary disappears; Iris later receives a new diary and note of apology. 
Question: Who does Iris confront when her diary disappears?
A:
a rich girl who was hired as a permanent employee
