You may need to rephrase this question as you provide an answer because it can be difficult to determine what a colleague's fair share of work is. Unless you are their manager, you may not understand their work responsibilities or arrangements. Provide an answer that generally explains what you expect from working as a team and how you would address conflict amongst team members.

"When working as part of the team, the ultimate goal is a successful outcome for the client. Sometimes that means taking on more work to ensure it gets completed. Colleagues are humans and things come up that can affect work. I believe it's important to have clear communication with each other so we can understand how workload is being distributed amongst the team."
