Hi, I recently completed my CNA course and started looking for jobs through agencies. One particular agency call me, I filled out the application, the same day I got called to attend orientation. At the orientation, I signed everything I had to sign and was given a name tag. But now it's been weeks, with no start date; I called them and they told me if they don't call me, it's because they don't have a case for me yet. Is this normal or did they hire me just in case they might need and should I start looking elsewhere?
