   Thanks for bringing this to me. I can't commit my time to leading it, and that's about my time, not a judgment of the proposal. Shall we think about who else could lead it?

   Someone you manage · Chat

   Pick this when someone you manage wants you to sponsor an unpaid initiative, because it protects their confidence and offers a next step.

Examples

What to avoid

• Making up an excuse you may have to keep up later, when a short, true reason is enough.
• Saying “maybe next time” when you don't mean it.
• Explaining too much, which invites the other person to negotiate.
• Staying silent instead of replying, which feels worse to the asker than a polite no.
