The social work has change from a voluntary dedication to an established profession. Social work is a profession in constant change and development. This study is about how social work has changed over time and how these changes have affected social workers professional practice. Our study highlights the changes in Sweden in the last 30 years. Our study is a qualitative study with an individual perspective and was conducted through semi-structured interviews with social workers over 55 years old. The results were consequently analyzed by using organizational theory, new institutonalism, professionalism and specialization. The result showed mainly three changes. These changes were digitization, streamlining and specialization. The result showed that these changes have contributed to both positive and negative consequences. Some of the consequences are; less client contact, high workload and more administrative work. The social work is changing as society develops. The result also shows that the professional identity is complex and associated to many other things. The disadvantage of the social worker's professional profession is the complexity, because social workers are a professional group with broad knowledge who can work in many different fields, which means that a professional identity can be  difficult to create.
