I'm in a bit of a pickle my friends and need some help to try to try to save myself.

I am a partner of over 12 years and have NEVER had an issue with money until recently. In December I came in to work one day to close and our opening SSV asked me what I did with a deposit from 4 days earlier. I told her I put it in the safe but she told me that it was not there. I know 100% that I dropped the deposit because I had a $10 overage the night of the deposit in question and wanted to ensure I dropped the money correctly (in case the 10 was from the float/til/extra to add to the deposit).

Today my manager asked me again where the deposit could be and I literally told her what I know happened, I dropped it in the safe that night so I have no idea what could have happened.

Is there some way to track door 2 activations throughout the week? I am at an absolute loss and my manager basically warned me that next step is an investigation and whenever those happen a partner is typically terminated for it.

I also don't want to get too paranoid but I also fear that ANOTHER SSV at my store did something when checking door 2 as that's the only other way that could explain the missing bag. He has been trying to transfer out for a month now and I've always felt he wasn't a big fan of me. But it could also be all in my head.
