Only when you reach the middle level do you realize that the leaders above actually don't care at all about how much work you have done.

Only when you reach the middle level do you realize that the leaders above actually don't care at all about how much work you have done. Instead, they care about whether you are worthy of their trust and what problems you can really solve! This is also the unspoken rule of survival in the workplace and the ability that leaders with normal thinking value when selecting talents! Even if you work very hard and bear hardships without complaint, if you can't achieve the above two points, you are just a pair of hands. That is what we often call result-oriented and emotional value.
In fact, thinking from their perspective, leaders are also human beings. They have a lot of things to do. When there are too many things, they also have headaches. They also have things that they can't handle. If you are on their side and can solve problems at the same time, it will naturally make them feel at ease and they will naturally value you!
Therefore, if you want a promotion, a pay raise and make achievements, don't lie flat. You need to change from "doing things" to "solving problems".
Several methods to learn upward management:
In the unit, you must remember: no matter how big the matter is, it will pass. Remember that when only you are worried about this matter, it proves that this matter is not a big deal at all. So mentality is very important.
Some things disappear if you drag them on. So no matter how big the matter is, it will pass.
I once encountered a problem and was so anxious that I was ready to resign. As a result, after a few months, the leader said this was not a big deal.
When I am anxious, I am really anxious. I also thought about resigning, but after that period, there is nothing again and I return to normal life.
When a taciturn employee who is diligent in work and outstanding in performance becomes negative, complaining and depressed due to hopeless promotion and unfair treatment. Suddenly one day, he no longer complains and becomes reclusive and mature. Either he is ready to lie flat, or he has made a grand "escape" plan. I think the latter possibility is relatively large.
If one day the leader talks to you in private, shows concern and asks about your family life and other things outside of work, then it is very likely that the boss has other work arrangements for you. For example, your next workload will be relatively arduous and the responsibility will be relatively significant, even beyond your tolerable range.
