Seasonal hiring: what is paying well this year? after 18 years as a software tester

A retailer and two warehouses near Knoxville are hiring seasonal staff. I have been trying to stay organised about it. Hours ramp up in the coming weeks. Is it worth applying to several at once?

Ask early about permanent openings. Some teams fill them from their seasonal list.

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