Do what you can to strengthen your relationship with your immediate supervisor. In fact, the most important thing is to have a good relationship with your supervisor. You don't have to become best friends (it's better not to), but if you want to be with your company for a long time, you will need to develop a friendly and respectful relationship with your supervisor. Even if you don't always agree with her or him, try to be respectful and keep a good mood in the presence of your boss.
If you want to complain about something, express your grievances calmly, don't blame the supervisor and don't act as if you don't feel grateful for the opportunity to work.
Try to get to know your supervisor better and ask him or her questions about his or her plans or family. If your manager talks easily about his or her life, take an interest in what he or she has to say.
Keep a positive attitude. If you intend to keep your job, you need to feel good about it. Of course, work situations vary, but you need to remind yourself of what you like about your job and put up with the unpleasant aspects associated with it. Try to complain less about your job and talk more about what you like about it. Your supervisor is more likely to want to keep your job if you have a positive attitude and keep morale up in the office.
For example, if you're a teacher, you probably don't like checking tests and assigning grades. Don't complain about that, but rather talk about how you enjoy working with children.
