Pizza Hut

So I got hired 6 months ago. I was hired in as a shift lead deu to past pizza expriance. After the first week of very little training from my rgm i was put as closing manager. On my second week of work I was closing on my own with no extra manager in the store. Then very soon after a 100$ bill went missing out the safe over night. I was questioned about it, but I knew nothing of it. I later found out that the rgm had put one in the safe out of his own pocket to make the safe right. Then about a week later a pice of glass broke. It did not happen on the shift but was a huge mess the next morning. Again I am questioned over text and again I know nothing about it. For the next few weeks my boss starts leaving work earlier and earlier. Till about a month ago when he starts to come in clearly not in a right state of mind. Even after being told he was getting a promotion. He was sent home at least 3 times leaving the store in a state of termoil. Then he talked to the boss above him and got vacation time for a week, after a month of not doing his job, then comes back to the store. While he hadn't been there doing his job the month before his vacation we had no money issues is the store, but magically as soon as he returned the safe was short 120$. Our store has no camaras because npc is to concerned about being liable for robbery that they would rather let there employees be completely unprotected as the person that they have running there store can do anything and blame it on anyone. The other managers are also upset with this but little to nothing has been done. Npc needs to change.
