Yeah, I had a couple of screw ups with sim schedules. I got a call one day from the training department about 2 hours before a scheduled sim at 3 pm telling me that “You missed your sim this morning at 6 am.” I said, “No, we’ve got a sim at 3 pm.” Her, “Yeah, they changed that yesterday but forgot to email y’all.”
Happened again the next week but thankfully the instructor emailed us to let us know. Seems like they change the schedule but forget to notify everyone.
