Yes because social work is working with people socially and teaching is social because you have to connect with the younger generation (AKA. Children).
It is better to update both iPhones using the same lines other than downloading another IPSW.
Usually, to become a social worker, you need at least a Bachelor's degree in a subject related to psychology or counseling. Some agencies even expect a master's degree in social work, called a "MSW". However, there are also people who major in something outside of social work (like business), and minor is a subject that can lead to a career in social work. If you at least minor is a social-work related subject, you should be able to find work in that field.

Social work is closely related to other social sciences such as psychology, sociology, and anthropology. It draws on theories and methods from these disciplines to understand human behavior, social systems, and societal issues. Social work integrates knowledge from various social sciences to address individual and social problems, promote well-being, and advocate for social justice.
