You agreed that a shared task would be finished on Thursday, but it has slipped several times. You complete it yourself each time to avoid a problem on Friday. The arrangement on paper and the arrangement in practice are now different.
Choose a recent example and discuss what happened. Ask whether the timing, information or ownership was unclear. Explain the effect on your own work without adding a general verdict about the other person's character.
Decide on a workable change
You may need a different deadline, an earlier check or another owner. Confirm the revised arrangement and what happens if it cannot be met. Avoid proposing a consequence you do not intend or have authority to apply.
After the next attempt, review whether the change helped. If the task still repeatedly falls to you, raise that workload directly with the relevant person. A reminder alone may not solve an arrangement that asks for more time or capacity than someone can give, and silently covering it leaves that problem difficult to see.
