How should James handle the situation where his colleague routinely leaves his computer and monitor on at the end of each workday?

The best approach for James to take is to remind his colleague and explain that the company policy requires all employees to turn off all computers and equipment at the end of the day. This option promotes a collaborative work environment where employees can communicate openly and respectfully with each other about operational procedures and expectations.

By addressing the issue directly with Jiang, James provides an opportunity for his colleague to understand the importance of adhering to company policy, which often includes energy conservation, reducing operational costs, and maintaining equipment longevity. Open communication can help foster a culture of accountability and teamwork, encouraging everyone to take an active part in maintaining workplace standards.

The other choices do not facilitate constructive communication or resolve the issue effectively. Ignoring the situation ignores the potential negative impacts on the workplace, while reporting to a supervisor might escalate the matter unnecessarily without giving Jiang a chance to correct his behavior. Turning off Jiang's equipment himself might lead to misunderstandings and undermine personal responsibility, which could harm the professional relationship between colleagues.
