Confirm the Details With a Replacement Volunteer
Save the person's job and hours in Proximatic, then tell them and the lead where to meet. The roster shows who's coming in place of the volunteer who canceled.
Someone said yes to covering a shift. Finish the job while you have their attention: tell them exactly what they've agreed to and put their name where the event team will look for it.
For a replacement greeting guests on Saturday, a useful confirmation is:
Thanks, Casey. You're confirmed for welcome on Saturday, 8:45–11 AM. Meet Morgan at the east entrance at 8:45 for the briefing. You'll be greeting visitors and directing them to registration. Morgan knows you're taking the shift.
In Proximatic, save Casey's assignment in the place left by the cancellation. The event roster shows Casey beside the job and hours. When you're preparing the entrance crew, you can see who's coming without searching your messages for the person who said yes.
Send Morgan the same update. If the lead still has the old volunteer's name, even an enthusiastic replacement can arrive to a confused welcome. With the roster updated and the handoff made, Casey can get straight to the briefing and Morgan can concentrate on opening the entrance.
Create your event and organize the volunteers.
