Seasonal hiring: what is paying well this year? after 12 years as a machine operator

A retailer and two warehouses near Toledo are hiring seasonal staff. I am in Toledo, in case local advice matters. Hours ramp up in the coming weeks. Has anyone been converted to permanent?

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.

I was converted after one season because I showed up every day and volunteered for extra shifts. Managers remember that.
