Hey everyone and thank you for taking time out of your day to read this post.

Long story short I work in a restaurant as a bar manager. In this restaurant, though it is not legal, we are allowed to enjoy shift drinks. At first it was 1 drink a night per employee, and this could be any drink whether it be a cocktail, beer, wine, sangria, etc. Obviously this got out of control real fast, to the point where teenagers and minors are drinking occasionally, and the staff is having as much alcohol as they please. This includes myself. However, my manager, who's name I will not say, drinks the most out of all of us. Like a lot. It's also worth noting that she is now the 4th manager in that restaurant with a drinking problem. Normally it does not bother me, but a few months ago after she had been drinking she told me during an argument that it was a good thing that people I know have killed themselves. This angered me so I went to management, and they did nothing. Yesterday I missed a shift because I was not on the schedule, and I did not check the schedule change saying I was supposed to work. Today I was asked to sign a written warning about the situation, which I refused. She didn't get a written warning, so why did I and why should I have signed it? I angrily left the restaurant and called the person above her who is ignorant to the problematic drinking and spilled the beans about everything. Tomorrow I have a meeting with him to tell him everything that has happened and has been happening. Should I go through with the meeting and let him in on everything? Or should I let it slide and move on with my life. All answers are appreciated.
