Seasonal jobs that might turn permanent (update)

A staffing agency says some roles convert to permanent after 3 weeks. This is my first time dealing with any of this. I would like to avoid a gap in my résumé.

Thanks for writing this out. I went through something close to it 7 months ago, and it got easier once I kept a simple log of every call and form.

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