Nearly all shifts posted on our platforms are open to sign-ups on a first-come-first-served basis. It is also worth noting that we have tens of thousands of workers signed up on our app in every city we operate in.
Given that, there is high demand for the jobs posted on our platform and sometimes get filled seconds after being posted. So it is possible that you tap on a notification fairly quickly but still miss being able to sign up. While we understand that can be frustrating, it is inevitable that it'll happen every now and then. We thank you for your understanding and please know that there will be other shifts where you will have the opportunity to sign up.
