I feel ur pain. I have been here for over 4 plus years now, I am also on the flex board. However, I am on the PM flex, i go in at 4 or 5 work the outbound dock and if I am lucky I get a short linehaul run, if not, I go home after 4 or 5 hrs. At my barn, there are 3 guys above me on the flex, and they have to call every day, there times vary just like yours. Sometimes there are 2 or 3 of us that start at 4 just to work the dock.
