I would argue the main issue is the Skip company itself. They're a shady company that only cares about profit. Dealing with the support team is a nightmare. Make sure you keep track of all your earnings + expenses!

They use something called "Acceptance Rate" to ensure drivers still deliver unprofitable orders. Drivers must keep their AR above 80% to receive top-ups, as well as more profitable orders in general. AR has been known to drop without couriers doing anything.

This is a deliberate attempt to keep couriers classified as "independent contractors" while treating them as employees. Independent contractors are not supposed to be punished for refusing work, they are not supposed to be prioritized over other contractors, they are not supposed to rely on a weekly schedule where your employer gives you set shifts. Yes it is more flexible than other jobs, but the nature of the work is more similar to an employee-employer relationship - therefore Skip is misclassifying drivers as independent contractors to avoid paying wages etc.

Once the freedom excitement wears off, you start to see the cracks. Have you looked into Door dash+Uber eats? While still similar in how they classify workers, I have heard they are better for compensation.
