Seasonal hiring: what is paying well this year? - what worked for you?

A retailer and two warehouses near Kansas City are hiring seasonal staff. I do not usually post, so bear with me. Hours ramp up in the coming weeks. Which employers treat seasonal workers well?

Keep everything in writing and save the confirmation numbers. It saved me later.

Keep a list of supervisors' names. A reference from one of them helped me land my next job.
