Set a Reply Deadline When You Ask Someone to Cover a Shift
Give the person time to answer while leaving time to ask someone else. Proximatic helps you find someone free for the shift and save the agreed assignment.
A replacement request needs a time for the answer as well as a time for the work. If you wait until Friday night for someone to cover Saturday morning, the next person has very little chance to help.
Choose a deadline that leaves a useful second attempt. For a Saturday 9–11 welcome shift, Thursday noon may give you time to contact another volunteer and get the entrance lead a settled plan before Friday ends.
Can you cover welcome on Saturday, 9–11 AM? Please let me know by Thursday noon. If you can't take it, that's fine; I'll ask someone else so we can finish the entrance plan.
Proximatic's Find cover gives that next attempt a head start. It finds people who can do the job for the full hours, without a clash with another assignment. If the first person can't help, review another suitable candidate instead of starting the eligibility search again.
When someone accepts, save them in the open place and tell the lead.
