Which of the following is a common ethical dilemma in the workplace?

Conflicts of interest represent a significant ethical dilemma in the workplace because they occur when an individual's personal interests potentially interfere with their professional responsibilities. This can lead to situations where decisions are made based on personal gain rather than the best interest of the organization or its stakeholders, compromising integrity and trust. For example, an employee may face a conflict of interest if they are in a position to influence a contract award to a vendor with whom they have a personal relationship, which could lead to biased decision-making and ethical breaches.

In contrast, the other options listed—such as excessive vacation time, overtime pay policies, and job promotions based on seniority—often pertain to workplace policies or practices that may not involve ethical considerations directly related to personal integrity or conflicting loyalties. These items typically involve organizational norms, labor laws, and employee rights rather than dilemmas that challenge ethical standards or personal moral judgment.
