I'm the bottom seniority reg/temp driver at my center. I call at 7am for driving, then at 4pm for reload. Here's the past two days, but it happens often... Call at 7 Monday morning. Not needed to drive, told to call back at 4. At 1pm, I get called about 5 times saying I'm to report at 2pm to make a pickup, then do reload. When I get the message, I call back at 3:30 to tell them that I just got it, but I'll be there at 5:45 for reload. Finish reload at 10:30pm. Today I get a call at 3am for me to work preload but don't answer. Call at 7am, no work, but I need to be there at 5:45 for reload. Get called again twice at 1pm with their other line. No message. This is freaking insane. If they need me to drive, tell me when I call. When they say I'm not needed, I do other work until I call back at 4. I can't be on-call 24 hours a day on a hope that I might drive for 2 hours, or that some preload guy might call off. How do you guys think I should handle this? I was quiet about other stuff they pulled thinking they can make my life crap if I bitch, but they're doing it either way.
