That's all well and good. I too get voice mails of the AUTOMATED system's calls. I cannot call back to get a human to ask for the job called out on. It goes on through the list of us in the pool, until someone accepts. Then, job is off the table. Nobody accepts? Job off table after so long anyway.
Thing is a full timer can be half into a shift say 6 AM to 2 PM, call out and you still need to go and be there at 6 AM. Which I've just started writing down the shift times, weather or not I was there at the start. As they tell me "already budgeted, planned, just go on and do what you can."
It genuinely is a big CF. And like I've said, it happens to others the same as me, the "bosses" have been told. "We'll look at it." Nothing is ever done, or if it is, it only worsens things.
On the surface it seems they do not care. Let the work go undone though, ... unholy Hell. Which I don't understand. They got people like me that want to work, yet rather have a set schedule. No, got to go jump through hoops until someone retires, is fired (highly unlikely), or quits.
Why not hire those wanting to do the work? Let us get on with it? Nah, too simple I guess. Again, not a planner but a doer. Think it's obvious to see why. If not, ... I lack patience for bull sh*t.
Ah, but I was snookered into another year of it. *sighs*
