Seasonal jobs that might turn permanent (update)

A retailer and two warehouses near San Diego are hiring seasonal staff. It has been weighing on me all week. 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.
