Temp-to-hire openings around Sacramento - first time posting

A retailer and two warehouses near Sacramento are hiring seasonal staff. There are 11 people counting on me, so I am trying to be careful. I would like to avoid a gap in my résumé. Is it worth applying to several at once?

Thanks for writing this out. I went through something close to it 14 months ago, and it got easier once I kept a simple log of every call and form.
