Quick Answer: Cancel 12+ hours before start for minimal penalty. If running late, notify support chat immediately. More than 20 minutes late \= no-show, which removes you from the shift and may cancel other bookings.
Details: Late arrival thresholds: 10+ minutes late impacts on-time score. 15+ minutes and we'll try to call. 20+ minutes triggers a no-show — shift is reassigned and your reliability score drops significantly.
Cancellation: 12+ hours before \= minimal impact. Within 12 hours (late cancel) \= significant score decrease. No-show \= most severe. Too many of either reduces shift visibility progressively.
If a shift was canceled by the customer, your score is not affected. Always check the app before heading out.
When to Submit a Ticket: Generally not needed for late/cancel situations. Only if an emergency with documentation caused a no-show you want to dispute. See No-Show Disputes and Policy\.
