I was wondering if they have to call a certain time to say they need you for the morning. I work preload start time is 430. Ill treat the morning like I will have to work but i don't want to sit around and wait for a call or not. oh yeah and I am new here, been checking out the forum for about the past month just never registered. I'm in college and been working preload for about 2 1/2 months so far.
