Background and purpose: Large and micro companies in the clothing industry are working with CSR in different ways and to different extent. There are clear differences between large and micro clothing companies in regard to how their CSR work looks like. This study is about to find out what the differences are between the large and micro companies and what underlying motives they have for working with CSR.Method: The method that is used during this study is a qualitative method. The qualita-tive method involves making a thorough investigation, which also results in in-depth answers and not just answers like yes or no. Results of a qualitative research are often presented as quotations or as a narrative text.In this study interviews are used in order to fulfill the purpose. Answers of how compa-nies work with CSR cannot be gathered just by asking a few standardized questions. In-stead an interview will allow us to come close to the company and understand the whole concept of their CSR work. The companies that have been interviewed are KappAhl, Intersport, Crazy Horse and Alinas.Conclusion: There is a lack of knowledge in the CSR field between large and micro companies. Micro companies do not have the same knowledge, resources or time as large companies have. A difference that has been shown is that the micro companies do engage in CSR activities, although in a small scale compared to the large companies, even if they do not know it themselves. Large companies engage far more in CSR activ-ities and spend a lot of resources on these kinds of activities.The large and the micro companies also have different motives for working with CSR questions. There is a difference between newly established micro companies and micro companies that have been around for a while. The new companies do actually thinkabout CSR and believe that it is important that they are socially responsible, even if they do not have the resources to actually engage in different activities in order to do so. The well established micro company on the other hand does not think that much about CSR and use the same suppliers as they have always done.A clear motive why large companies as KappAhl and Intersport work with CSR is that they want to give something back to the world. Therefore they engage in activities where they have their operations in order to create a better environment. They take their responsibility even externally and not just internally, as the micro companies do.
