With references to book author year of publication and page number, what does Sheafor, B. W. (2000) Says on macro level of social work intervention?

According to Sheafor, B. W. (2000), on the macro level of social work intervention, "social workers are involved in activities that affect entire communities, organizations, or social systems" (p. 23). This means that social workers at the macro level work to create change on a larger scale, such as advocating for policy changes or implementing programs that benefit a large group of people.
