Professional ethics encompass standards of behavior expected of professionals. They prescribe rules for using knowledge when rendering services to the public. Some key aspects of professional ethics include striving for excellence, being trustworthy, acting with integrity, setting good examples, sacrificing present gains for future benefits, and maintaining high discipline. Business ethics provide guidelines that business houses should follow. They involve complying with the country's laws, ensuring profits while following ethics, considering stakeholder wellbeing, minimizing environmental impacts, protecting common resources, upholding employee security, and avoiding human rights violations like child labor and gender bias. Conclusions note that business ethical issues balance profits with non-economic concerns and are often developed through stakeholder consultations.
