She can easily be cloned in Create a Sim with debugging mode on. Like all social workers, it is possible to meet Social Worker if a playable Sim is lectured by her, without using cheats. However it is not recommended to try to build a relationship with her even if a friendship can be built safely by using the telephone.
Social Worker has 0 interest points in Sci-Fi, which is typical for deceased Sims, but not for adulttownies and NPCs, as they typically have 4 interest points in Sci-Fi.
Do NOT attempt to add Social Worker to a household, make her selectable, or tamper with her in any way or form. Doing so will corrupt the neighbourhood she is in.
Social Worker may be spawned as a blind date through the Gypsy Matchmaker. If this happens, delete Social Worker using the moveobjects cheat, or through testingcheatsenabled, and do NOT interact with her.
