Tell the Team Lead When a Volunteer Cancels
Tell the lead which job needs someone and who has agreed to take it. Save the replacement in Proximatic so the schedule matches the message.
A cancellation update should let the lead make a decision. “I've asked someone” leaves them guessing whether to prepare for a replacement or a smaller crew.
Tell them the job, the gap and what happens next:
Alex canceled Saturday's welcome shift, 9–11. I've asked Casey to cover and will have an answer by noon. The place is still open. If it isn't filled, we'll open the east entrance only.
Update the Proximatic roster as you find a replacement. Remove Alex from the canceled shift, use Find cover to find people who can take it, and add Casey after they accept. You can see the rest of the entrance crew while making the change, including whether anyone is already committed to another job.
Then finish the handoff:
Casey accepted and is on the welcome roster, 9–11. They'll meet you at the east entrance for the briefing. Both entrances can open as planned.
The lead now knows who's coming and which operating plan to use. When another shift changes, you have the jobs and assignments together instead of relying on whichever message the lead happened to read last.
Create your event and keep team leads up to date.
