Which of the following demonstrates poor professional ethics in a workplace?

Favouritism exemplifies poor professional ethics because it indicates a bias in how individuals are treated in the workplace, often leading to an unfair distribution of opportunities, recognition, and resources. When a manager or team leader shows preferential treatment to certain employees, it can undermine team morale, create workplace tension, and foster resentment among coworkers. This practice goes against the principles of fairness and equality that are central to ethical conduct in a professional environment.

In contrast, dishonesty may reflect poor ethics as well, but it can occur in various forms, such as lying or withholding information, which may not directly involve preferential treatment. Lack of communication, while detrimental to teamwork and productivity, does not inherently reflect personal biases towards individuals. Overwork can lead to burnout and job dissatisfaction, but it is often a result of workplace demands rather than an ethical choice made by an individual. Hence, favouritism stands out as a clear example of actions rooted in unethical behavior in a professional context.
