Common Mistakes When Expressing Uncertainty at Work
Mistake 1: Using “I don’t know” as a full sentence
This can sound dismissive or unprepared. Always add a next step.
Fix: “I don’t know off the top of my head, but I can find out quickly.”
Mistake 2: Over-apologizing
Saying “Sorry, I’m really not sure” too often can make you seem less confident.
Fix: Use a neutral phrase like “I’ll need to confirm that.”
Mistake 3: Being vague without offering help
“I’m not sure” without any follow-up leaves the other person stuck.
Fix: Always add what you will do next, such as “I’ll check and update you.”
