Jobs are as important for our characters as they are for real people. A character’s career might be their dream job or one they’ve chosen due to necessity. In your story, they might be trying to get that job or are already working in the field. Whatever the situation, as with any defining aspect for your character, you’ll need to do the proper research to be able to write that career knowledgeably.
Enter the Occupation Thesaurus. Here, you’ll find important background information on a variety of career options for your character. In addition to the basics, we’ll also be covering related info that relates to character arc and story planning, such as sources of conflict (internal and external) and how the job might impact basic human needs, thereby affecting the character’s goals.
We hope the sample list of ideas below will show you how to choose and use your character’s occupation to do more than simply reference a day job. For the full entry for this career and over 120 other ideas, check into our bestselling resource, The Occupation Thesaurus: A Writer’s Guide to Jobs, Vocations, and Careers.
