When to use it
Use it when you need to discuss something serious with someone. “We need to talk” creates dread. Naming the topic and suggesting a time lets them prepare and shows it's a work conversation, not an ambush.
Example
You: “I'd like 15 minutes to talk about the handoff. Does 2:00 work?”
Colleague: “Sure, 2:00 works.”
In an email or Slack message
In Slack: “Could we grab 15 min today to talk about the handoff process? 2:00 or 4:00 work for me.” Giving two times makes it easy to reply.
