There are many side hustles for social workers. If you want to use your skills and experience, you could create content (start a blog, YouTube channel, or podcast) on related topics. You can also create and sell printables related to wellness, mental health, and more. And if you're open to side hustles that don't involve your expertise, you can deliver food with DoorDash or take surveys at Swagbucks, InboxDollars, and Survey Junkie.
