Did you let them know that you are returning back? Even if your LOA has an end date , they will put you in schedule only if you call and let them know. I’m also going back next week and I called them couple of weeks before . I wasn’t able to see any schedule at first but then I called again. They Told they had me scheduled , which appears in the paper schedule but not in the system. Then again they added it to the system and now Kronos is showing my schedules.
