Peak pay is a bonus that's added to every order assigned during peak times. To find out when peak pay is in effect, click through the "Manage Schedule" section of your app. Peak pay will show in green lettering as “+15%,” “+20%,” etc., beneath the shifts for which it's in effect. These percentages indicate the extra amount that will be added to the base pay for all orders assigned during these shifts. Peak pay applies to everyone who works, scheduled or not.
When peak pay is in effect, pay on the order details screen will be shown as two separate totals: “Base Pay” and “Bonus.”
Note that peak pay amounts can change, and may not be in effect in all markets at all times. Any changes will be visible in the “Manage Schedule” section of the app.
