What would a typical work day be like for a social worker?
Most people going into the social work field have some college. Are you looking for something you can do directly after high school without going to college?
Given some of your other questions, I can tell you are concerned about the stress and emotional impact social work can bring about. I recommend you consider volunteering, to both evaluate if you like it, and also to get your foot in the door!
Here is a good place to start.
