I started my new career a month and a half ago, we are 8 new guys that started at the same time.
Everybody there hate their job, they hate that we ask questions and they don't want to show us how to do the job properly.
hopefully, there are a few young guys there who showed us a few tricks, but the old guys don't give a fuck and try to give us shit for no reason.
our formators told us to keep our mouth shut, and endure it until we are accepted.
7 of the 8 are doing this, myself I set the tone the first week by telling an old fucker than I am all for taking criticism, but that I am not a fucking dog and that if he doesn't change his fucking tone when he talks to me I'll play his game too.
needless to say, the 7 others keep getting shit on by everybody and nobody say shit to me and they answer my questions without arguying 
we dont choose to be alive, but we choose the way we live. For those who have a soul, who are conscious. Im not talking about animals who only think about themselves and have no problem surviving at the expense of others. In groups, people have to insure their own survival and have their own ennemies and people they like. Ultimately th same people stick together and are against others. You have traitors who go from one side to the other depending of what benefits them the most... Good old fight between good and evil, and everyone in this atheist world has his own view of what s good an evil... This is why life is so stressful, because not everyone think the same and because everyone imports his problems at work and thinks others are responsible for them, especially when somethign goes wrong at work. Fat people are jealous of leaner people, people always try to pretend, impress, because their private life sucks, you have liars who cant get track of their lies after some weeks...
There are old assholes who survived being assholes and destroying others. You also have good hearted people who survived being good hearted, and sometimes if the guys at the top of the pyramid at your workplace are good people, most of the hierarchy is made of people like them. But basically it's a giant free for all.
The key is not to become an asshole because people are. You have to stay faithful. The key is to understand you are not other people's problem. Most of the time i figure someone's weaknesses and break him or her by letting them know from the get go i know why theyre frustrated but that it's not my fault, and i do it publicly so everyone see them getting put in their place. At some point in life you re sick of having to endure other people stupidity and try to find a place where you belong, where you re with people like you and where you can contribute with the maximum of your best capabilities.
Old people have survived so many bullshit, fought every single day others, so they think that's how it has to be for any newcommer, that's its the rule of life, of the jungle, of nature. But old good people help young good people, and old bad people help young bad people.
