3PL Delivery Drivers - Delivering for SHEIN & Temu

I am an investigative journalist who just started covering 3PL logistics companies. What should I know? What is the worst delivery company to work for? I am a journalist who just started covering 3PL delivery companies. I am particularly interested in companies that do a lot of work for SHEIN, Temu, etc. I would love to speak with anyone who wants to connect and tell me about their experiences. Any insight into what it is like to deliver for one of these companies would be great. If you DM me, I will send you over my personal contact details so you can verify that I am a real person (just don't want to put it out on the open internet).
