Pros
For a small share of students who are homebound or can't access some traditional courses, you are a lifeline towards better education. The courseware is moderately well made up. As a teacher, you learn more about your course for the first few months.
Cons
FLVS undermines public education by hiring scab non-union teachers (such as myself) and threatens them to pass as many students as possible, no matter how badly they have not yet mastered the content "at their own pace". This is a call center, that plays by different rules than a typical public school, and used government lobbying to grow as large as they have. As an employee you have to deal with student cheating while never punishing students for doing wrong. Imagine being a manager in a bank, and seeing a teller steal money, and be told your job is to continue to support that teller because otherwise the whole operation will shut down.
