Team lead schedule

My store prints a team lead schedule for the month and posts it on paper at the time clock. I normally copy/ photograph it so I can plane my month. I had 2days off on the weekend. So I planed a date night with the wife because I barely see her any more. This schedule was posted after the closing lead quit and we have not had any more leads leave. I get a call right as we are sitting down for dinner that I was schedule that I should not follow the month schedule I need to do off the target my time app. What should I do. I can’t take anything to my Etl because they will automatically blow me off or had it to the person that the issue is about. I have tried ethics they get no were.
