How to Ask Someone to Cover a Volunteer Shift
Tell them the job, hours and when you need an answer. Proximatic's Find cover shows people who can take the shift, so you can choose someone to ask.
A volunteer has canceled the shift greeting guests on Saturday, 8:45–11 AM. You need someone to take those hours, and a general request for Saturday help leaves you explaining the job again to everyone who replies.
Open the shift that needs a replacement in Proximatic. Find cover checks who can do the job, is free for the whole shift and isn't already working somewhere else. You can ask someone who fits instead of working through a contact list and discovering the conflicts one reply at a time.
For a welcome shift from 8:45–11 AM, send a request like this:
Can you cover welcome on Saturday, 8:45–11 AM? You'll greet visitors and direct them to registration. Meet Morgan at the east entrance for the briefing. Please let me know by Thursday noon so I can arrange other cover if needed.
Once Casey accepts, save Casey in that open place on the roster. Morgan has the right person to expect, Casey has a definite commitment, and you can stop asking for help with a job that's now covered.
Create your event and find someone to cover a shift.
