Compliance (follow law) vs. Integrity (values-driven, culture that supports ethics)
Role of religion/spirituality/personal values in business. When should they be separate, and when must they align?
A company's role in individual freedom vs. protection of employees. If a company must restrict certain jobs to specific demographics due to safety reasons, is that discrimination?
Publishing as yourself vs. representing your company. This is particularly relevant today, where people have multiple social identities online (and companies have their own online identities as well). I think the most important thing is that people be very clear on whose thinking they are promoting and what interests and affiliations they have.
