where do you draw the line

I had kind of a rough day today trying to figure out where my job sits and where my morals are. I arrived at work to find out that one of our teachers was no longer on the schedule. There was an incident last friday where two or more teachers were involved and she was the only one that had been punished. She had tried so hard to eliminate the problem and everyone was telling her what to do but not helping. When those opinionated people were in the classroom also, the incidents still happened. There is one employee who has been with the company for ever. She was in the room and was never displined for the incident. Lets say that Hailey was the one punished and that Kathy was the other one in the room that did not. Hailey in my eyes has tried so hard to fix things and has taken it all apon herself. Yes she should have been more alert with the children and that somehting should have been done but why only her. I feel like it is because she has been around for a long time and she babysits the boss's kids for free. I don't know. It just torks me off how there is so many double standards. I am not arguing that she shouldn't have been punished, i just think that all parties should have had reprocusions. There are a lot of other things that "Kathy" does wrong in a day and nothing is said to her. Why is that? I know that if i say anything then it will cost my happiness at work.
On a better note, I am back on my catch. LOL. I am enjoying some dinner and my show. I have my big soft fleece blanket over me and i am totally relaxed. I had a long day after a late night last night so i need some rest tonight. i heard that there was an accident in new york and am glad to hear that my step mum is alright. She is going to call later and I am so excited. I am going to enjoy my evening by myself. I hope everyone else can enjoy their evenings too.
