Seasonal jobs that might turn permanent - 9 months and counting

A retailer and two warehouses near Cleveland are hiring seasonal staff. I have read a lot of threads here and could not find my exact situation. I would like to avoid a gap in my résumé. Has anyone been converted to permanent?

Apply to several. Start dates and schedules change quickly and having options helps.

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