I’ve finished an intensive 8-hour course in legal proofreading, and I plan on taking a test at one of the legal proofreading agencies in hopes of getting a job. However, the instructor did casually say that temps are “on-call,” and will be contacted if and when a law firm needs a proofreader. If this is the nature of legal proofreading, how will I ever get a permanent job or at least earn back the money I spent on the class?
