Seasonal jobs that might turn permanent - any advice?

I am looking at seasonal jobs around Knoxville that might lead to something longer. I am in Knoxville, in case local advice matters. I would like to avoid a gap in my résumé. Which employers treat seasonal workers well?

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

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