Seasonal hiring: what is paying well this year? (update)

A staffing agency says some roles convert to permanent after 17 weeks. Any experience at all would help. Hours ramp up in the coming weeks. Which employers treat seasonal workers well?

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

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