Temp-to-hire openings around Boise - what worked for you?

A retailer and two warehouses near Boise are hiring seasonal staff. It has been a long 11 weeks. I would like to avoid a gap in my résumé. 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.
