All the clues are pointing to Steve, but he keeps insisting that it is the lower-level employees. He keeps pointing the finger at them. All cash shortages are reported to the corporate office employees of the company. This loss of money poorly on your management skills. You regret not having reported it earlier.
The cash drawer is always short of a few dollars. I have an idea of who it is.
Steve realzies that you have proof of his unethical behaviour and proof that his behaviour is harming the company. You also believe that their have been other instances of Steve behaving enthically, but you are unsure of what actions to take.
I have proof of what you have been doing. This unethical behavior of yours is unacceptable.
Oh no! She might actually have proof.
You decide to go to the District Manager with the proof, regardless of your relationship with Steve, his unethical behavior is harming the company. Also, you don't want someone else being accused and possibly fired for his behaviors.
