Amazon A to Z

I have been working for Amazon for a year and using this app (AtoZ) to pick my shifts and keep track of my PTO (paid time off). Last week it all of a sudden stopped keeping track of my PTO… which means if I’m running late or I’m sick or any reason I need to use my PTO I can NOT!
I have opened up many tickets regarding this matter and nobody has fixed this issue!
I’m going on 12days now not being able to request PTO. If Iam late, or can’t show up for a shift employees get occurrences, 3 occurrences and your terminated! THIS IS ABSURD THAT AMAZON HAS NOT ADDRESSED THIS ISSUE.
NÉXT STEP IS TO FILE AN ETHICS CLAIM!
SHAME ON AMAZON FOR NOT ADDRESSING THIS VERY IMPORTANT ISSUE THAT CAN RESULT IN MY TERMINATION!
