It depends on your building and what state you're in. I'm assuming you're a packer. Just ask any warehouse worker.
Outbound, Inbound, Warehouse, and E&F UA's all make the same.
Mechanics make more and are broken down into Mech 1 and 2 with Mech 2's making more.
Any clerical, asset protection, ICQA and HR are on a merit based pay scale and starting pay can vary based on experience and what you're currently making but they're all interview positions and need to have openings.
