ShiftWell
Open shift at 3am? Covered by breakfast.
Post a shift once. ShiftWell finds who can safely take it, and lets the first one claim it.

Your whole team
Staff can pick up shifts regardless of job or credentials, within company working-hour rules.
One shift, one person
Claims are reserved instantly, so two people can never book the same shift.
Nothing slips
Managers hear when a shift fills — and get an alert when it doesn't.
