How to Cover a Volunteer Shift With Two People
Give each person their own hours on the Proximatic schedule. See which part of the job is still open and arrange time for one volunteer to explain the work to the next.
A volunteer has canceled the 9–11 shift greeting guests. Someone else can help, but only from 10. You can use that offer if you find a person for the first hour too.
In Proximatic, make those commitments separate shifts: welcome from 9–10 and welcome from 10–11. The later volunteer can take the work they can actually do, while the earlier opening remains visible. You get a specific request to share: one person to greet guests for the first hour.
Use Find cover on the earlier shift to find people who can greet guests from 9–10. If Alex agrees to take 9–10, save Alex there and the later replacement in 10–11. The roster now accounts for the whole morning instead of showing one name beside a two-hour promise they couldn't keep.
Where the desk needs a handover, include a short overlap in the hours both volunteers accept. The incoming person can learn what's happening before the first person leaves. Plan that time along with the work and the lead can open the desk knowing who takes over next.
Create your event and fill the hours that need help.
