Avoid casting any coworkers or supervisors in a negative light. Choose an example that advertises your integrity. Offering a situation where an honest mistake or human error was made and how you went out of your way to make right could serve you well here.

"A coworker struggled with showing up to work on time. They'd recently been reprimanded for it. When they missed their bus again, they called me with excuses for their alarm not going off, etc. When I asked them why they were calling me with this concern, and not a supervisor, they said they were hoping I would clock in and lie for them. I explained I wouldn't do this and suggested they talk to a supervisor, give them a heads-up that they were delayed, and take responsibility for their own actions. They said they were going to, hung up, and then instead called out sick. They then called another coworker and asked them to take on their workload. I grappled with this and decided their attendance issues weren't the only problem here. They were slowing down the productivity of the rest of the team, creating a negative work environment, and overburdening other members of the team by passing off their work. I felt resentful of the awkward position this coworker put me in, and decided, regardless of how awkward, that I should let management know. I did, and the issues were addressed. I was worried other members of the team might resent me for my decision, but it turned out most of them supported the choice I made."
