I don't think it's wrong for you to be unsociable, not to flatter the leader, and just to get by, but it's easy for you to make yourself a target. Because in business, or in a group, you have to mingle with others if you want to fit in. You have to perform well and get along with the leaders if you want to get promoted. You just have to remember that there is nothing wrong with you, but one has to learn to adapt to the environment rather than letting the environment adapt to you. As long as you figure this out, you won't get hung up on right and wrong, and you'll be able to live a little happier whether you're working or living.
Many people want to live a peaceful life in the enterprise, but the reality tells you that this is impossible. Because in the enterprise to talk about corporate culture, one of the articles is to make good relations with colleagues. If you want to fit in, you have to mingle with others, you have to socialize and socialize. This is a lesson that adults must learn as they enter society. Maybe you don't like your coworkers and don't want to deal with anyone, but it's part of your job description, and you'll only be able to survive in this group if you get used to it. Don't worry about it too much, think of it as a difficulty you have to overcome at work, and you'll realize that it's not that hard to socialize and deal with people.
If you don't flatter the leader, you'll have even fewer dull days to live. You can only get promoted if you have a good relationship with your leaders and show your face in front of them more often. Generally you want to live a more comfortable life in a company or a team, you must wait until you have stood on a high enough position. So you not only have to work hard, but you also have to follow the leader's lead so that you can realize your desire to live an ordinary life sooner.
In fact, you have to realize one thing from the day you start working, people have to adapt to the environment, rather than letting the environment adapt to you. As long as you understand this, you will be able to stay well in the unit, and even achieve good work performance earlier.
So, while there is nothing wrong with you being unsociable and sucking up to the leadership, as long as you still want to work, you have to learn to adapt to it all.
