There are several aspects to completing business ethics research.
First, you need a Fortune 500 company. Click on this link to find some companies and even search by industry. Get creative! Remember, you can't write about the same company as anyone else in your class. Read about social issues that impact businesses in the specific industry you choose. Click on the "Social Stakeholders" link above to get a clearer picture of the business issues which impact people. You can also take a look at the most ethical companies compiled by Ethisphere. Don't want to write about companies who are trying to be ethical? Covalence put together a list of the top twelve least ethical companies.
Secondly, you're going to want some company information. Click on the "Company Information" tab to search databases by company name. Perhaps you're researching laws on cigarette package labeling. For instance, cigarette manufacturers have taken the words "light" off of cigarette packs in the United States. This could impact Corporate Social Responsibility (CSR) -whether it's the result of government regulation or other factors. For instance, with cigarette and tobacco companies, there's industry-wide changes to consider such as the increasing popularity of e-cigarettes. Once you've gotten some background on social stakeholders, it's a good idea to research within that industry (i.e. tobacco companies such as Philip Morris or Reynolds American).
Then, it's good to find some articles on the company and social stakeholders. These can include journal articles as well as newspaper and magazine articles. Hint: many of the databases located on the "Find Articles" tab allow you to narrow the search to both full-text and scholarly or peer-reviewed journals. Why is this so important? If you're off-campus, you can still get plenty of journal articles in full-text right from Old Westbury Library but you have to let the databases know this is specifically what you want. Once inside the database, you'll see helpful links to narrow your search.
