When a person gets a new job, he thinks, of course, first of all about earnings, and not at all about friendship with colleagues.
It’s good if he comes across a friendly team that happily accepts the newcomer and helps him get settled in.
In principle, the option where each employee is solely dedicated to their own duties is also relatively acceptable.

The worst situation is when a newcomer is clearly not accepted and no one even tries to hide it. This happens primarily in toxic groups, where someone has to be bullied.
It is useless to try to find a common language or have a heart-to-heart talk with such people. If they have decided to mock or ignore, then it is unlikely that they can be stopped.
The reason for such a choice is usually one: the employee was unable to fit into the accepted norms and is too different from his new colleagues.
What should he do in this case? As has already been said above, any attempt to establish communication is doomed to failure. It is the same as voluntarily accepting humiliation.
In addition to being branded as strange, people will also ridicule their good manners and politeness, which will be considered to be sycophancy and fawning. But is it possible to work in such conditions?
The most effective advice for someone who has become an outcast in the workplace.
Keep calm and do your job
In the end, everyone goes to work first and foremost to earn money. That's what you need to do, not count sidelong glances and eavesdrop on whispers behind your back.
It is not at all necessary to be liked by colleagues, especially if they are distinguished by a rather low level of social responsibility: they like to gather at a club on Fridays, drink, and meet dubious individuals.
Why be like them? But even if they position themselves as serious and responsible people, you still shouldn't become one of the grey mass. It's always much more interesting to be yourself, and not part of a large community.
In addition, if an employee does not run every hour for a smoke break and does not sit in the canteen during lunch break, then he is much more productive. Instead of aimlessly spending time, he gradually gets into the work and shows good results. And this is much more important for the management.
Try to get closer to the manager
Since the team still didn't accept it, then perhaps it makes sense to become the director's confidant. If he is a normal and businesslike person, he will definitely meet you halfway and help.
Personal assignments, promotion, salary increases - all these are important factors of such cooperation. There is nothing terrible or shameful in this: everyone does their best.
Don't look for flaws in yourself
Usually people immediately start blaming themselves, delving into their own emotions, working on themselves instead of just living calmly.
Yes, the team didn’t like me, so what, should I blame myself for the rest of my life?
It is important to love and respect yourself first of all. When a person has low self-esteem, others immediately feel it and try to play on it.
They stoop to insults, raising their voices, accusing you of this or that action; in a word, emotional pressure begins on all fronts.
This cannot be allowed in the workplace because such abusers are a herd that is incapable of logical thinking.
They just throw themselves at the first person they meet if that person allows them to. The more people respect themselves, the faster toxicity will disappear from communication.
Of course, there are employees with a delicate mental organization. They are impressionable, tearful, emotional, and worry about every poorly spoken word or careless gesture.
It is imperative to fight this or, at worst, not to demonstrate these personal qualities at work.
Here, everyone is for themselves, so sympathizers or understanding people are unlikely to be found. But there will definitely be a discussion about how violently a newcomer reacts to a joke or a mean joke.
The conclusions that will be drawn from this will be completely unambiguous, which will serve as an additional reason for persecution.
Since he can’t stand up for himself, he’s a typical victim on whom you can take out your bad mood.
Earlier I talked about why people don’t value themselves.
