Which outcome could be considered an adverse action for a professional?

The outcome of license suspension or revocation is indeed considered an adverse action for a professional. An adverse action typically refers to any decision that negatively impacts an individual's professional standing, ability to practice, or overall career trajectory. License suspension or revocation directly affects a professional's ability to work in their field, potentially leading to loss of income, reputation, and career opportunities.

In contrast, receiving commendation for service excellence, promotion to a higher position, or increased client referrals are all positive outcomes that enhance a professional's standing and career progression. These outcomes indicate recognition of good performance, advancement in career status, and growth in client relationships, which do not align with the concept of adverse actions.
