We had a supervisor who was struggling to motivate their crew. To incentivize, this supervisor was abusing the manager's expense account, treating their crew to breakfast at the end of each shift. Their productivity hadn't increased, and expensive breakfasts were being taken for granted. My superiors asked me to address this. My conversation with that supervisor had little impact. I was in charge of scheduling and traded shifts with this supervisor. They didn't prefer the midday shift. Neither did I prefer the morning shift. At first, it upset the morning crew that they had to provide their own meals. But under my supervision, productivity and morale improved, and our superiors could further develop and direct the supervisor who was struggling with incentivizing their crew.

This one is a balancing act. Not only does this high-pressure question test how you respond under the pressure of the question itself, but it likewise tests your outlook. You'll want to focus not on any one person, but frame your answer by presenting the situation. Avoid framing yourself as unpopular. Instead, frame the decision as unpopular, but made on behalf of the greater good.
