I'm on reserve. Pulled my schedule on CCS at 1815 Local PDT and no assignment on my schedule. Then I check my schedule at 2045 LCL and I've got an 0600 short call. Not really a logistical problem for me as I live in base but if I was a commuter, I'd be in a bind for sure. So to my point, how do I determine what time they assigned me the short call.
