Hello, I was just hired as a PT package handler. Had interview a couple weeks ago, was offered the job, and had orientation yesterday. Was told after talking to my manager that same day that I have on-call status and would need to call in before coming into work. Today (which would've been my first day), was told I was not needed today and to call back the next work day. Anyone have any idea why this would be the case? Is the on-call status for a new hire a temporary thing? I'd love to get started but this gets me a little nervous. Would greatly appreciate any insight or ideas.
