Seasonal hiring: what is paying well this year? - first time posting

A staffing agency says some roles convert to permanent after 4 weeks. I have read a lot of threads here and could not find my exact situation. Hours ramp up in the coming weeks. Is it worth applying to several at once?

Thanks for writing this out. I went through something close to it 9 months ago, and it got easier once I kept a simple log of every call and form.
