This portfolio presents a reflective analysis of three seminars focusing on Corporate Social Responsibility (CSR), whistleblowing, and the role of social media in business, particularly for Small and Medium Enterprises (SMEs). The first seminar explored various CSR approaches (volunteerism, environmental conservation, diversity and labor practices, and philanthropic efforts) and their challenges for SMEs, including the financial burden of mandatory CSR obligations. The second seminar delved into the ethics of whistleblowing, contrasting its benefits for stakeholders in revealing organizational wrongdoing with concerns about confidentiality and workplace ethics. The third seminar examined the use of social media by SMEs, highlighting its cost-effectiveness for marketing and communication while acknowledging potential difficulties such as brand image management and increased competition. The portfolio synthesizes the learnings from these seminars, comparing arguments and reflecting on the impact of these topics on business practices and ethical considerations, emphasizing the interconnectedness of CSR, ethical behavior, and strategic use of social media in the business environment. The author concludes with a summary of the key takeaways and the evolution of their understanding of the topics covered.
