When to use it
Use it when you're making a request and want to be considerate. Offering to work around their schedule is gracious. Adding “no worries if not” invites the other person to say no before they've even thought about it.
Example
You: “Would you be open to a quick call Thursday? Happy to work around your schedule.”
Mentor: “Thursday at 4 works.”
In an email or Slack message
By email: “Would you be open to a 20-minute call next week? I'm flexible on timing, so any slot that suits you works for me.” Flexibility on how, firmness on the ask.
