I've worked multiple part-time jobs for family owned businesses that had a strict rule against hiring you if you worked or planned to work another job (I don't even know if these questions are legal for them to ask). I've always liked working two part time jobs over one full time job. I never had to worry about getting fired or one of the businesses closing because I would still have another income. Plus, if I needed I could just ask the other job for full-time hours.

I've always been a good worker and never call in, and always pick up sick co-workers shifts. I've never been fired from a job either, but I still don't like the feeling of having my entire livelihood and income tied to one person. It's also way more stressful to have to find a new job if you only had one to start. Working two jobs also let's you take a longer time to hunt for a new second job instead of feeling pressured to take the first offer you get.

I know people who hate working two jobs and would rather work one job and get full-time benefits, but I also think working two jobs shouldn't always be thought of as a bad thing.
