Pros
You are on your own. You only contact dispatch if you can't reach the customer.
Cons
Poor customer service and terrible communication. I was explicitly told that W-2 couriers are scheduled for 4 hours per shift and would be paid the full 4 hours even if deliveries were completed early. That was not true.
I was only paid from the time I picked up packages until I completed my last delivery. For the past two weeks, I consistently started around 3:45 PM and finished by 6:45 PM, yet I was paid only for that time. In total, I was paid for 14.6 hours instead of the 20 hours I was told I would receive.
This is deceptive. The miles driven, the wear on my vehicle, and the risks involved are not worth being shorted on pay. If you are going to pay only for active delivery time, be honest about it upfront instead of misleading workers to get them onboarded.
