W2H does not provide a method for helpers to confirm or verify each shift assignment.
We recommend that you ask your helpers to review their email notifications and shift assignments for the week and then click the email notification link at the bottom of their schedule email (or schedule change email) to confirm receipt of the schedule.
This will trigger an envelope with a checkmark icon on the By Helper and Statistics schedule views, so that coordinators can easily see which helpers have confirmed all their shifts for each week.
You might consider posting a reminder to helpers to confirm their emailed schedules and shift changes on the Helper Homepage Notice.
