1. First of all, immediately keep all work materials, including emails sent by leaders when assigning work, completed work documents, PPT, etc. In case they don't recognize it later.
Practice is the sole criterion for testing truth
Seeing a lot of work coming, what should you do first? Whether the boss is picking on you or not, shouldn't you finish it first? Otherwise, is it even more criticized?
No matter how wronged you are, you should also know that you are paid by the boss of the enterprise, not by the boss. This is not a lofty slogan, but a code of conduct that should run through your whole career. As for fairness, should we wait until the company's work is finished? Only by successfully completing the work practice can you explain your personal ability, give you an opportunity to discuss with your boss, and also test whether you are a person who is not worth recommending by your boss, right?
2. Communicate frankly and one-on-one, express your questions and demand fair treatment. If the leader doesn't mean to embarrass you, generally speaking, he will seriously consider your suggestion, either give you a promotion or send you less work, that's all. If the leader really deliberately makes things difficult for you and prevaricates with all kinds of high-sounding reasons, indicating that direct communication with him at this time is invalid, then proceed to the next step.
3, leapfrog to the next higher level leaders to reflect the problem, the suggestion is well-founded, objective and rational, you can make an appointment for leadership time in advance by email. If some colleagues have been treated unfairly, they can unite to reflect and attract the attention of the big leaders. If the big leader agrees with your problem, I believe the problem will be solved soon, and the incident will end here. If the big leader is on your immediate leader's side, then this road won't work, so the next step.
4. Submit the collected evidence materials to the personnel management department of the company, reflect the problems and apply for transferring from the post. Generally speaking, large and formal companies will have a high probability of properly handling such problems. If it still can't be solved, go to the last step.
If you don't want to leave your job, you can slack off for a while. If the immediate leader finds that the work assigned to you cannot be completed, he will naturally hand it over to other colleagues. In this case, the chances of promotion and salary increase are slim. If you are willing to leave your job, apply for leaving immediately and prepare your resume to find a new job.
Gold always shines.
I believe many people have seen Du Lala's promotion. If you are competent enough, you can finish a lot of work assigned by your immediate supervisor and exceed it. Then I believe that your contribution will not be buried, at least no one will see it, and no one will impersonate your work. So, for you, you just need to wait for someone to find out. Don't say, someone will bury you on purpose, at least your immediate leader won't do so, because it is hitting him in the face. Don't say that someone has taken credit for you. Do you think it is necessary to stay in such a company?
Finally, the workplace, like a battlefield, needs a lot of wits and wits. At first, momentum was important. Don't be a good person. Don't give leaders and colleagues a feeling that you are weak and will take advantage. Don't rush to work if you don't agree. It is easy to be regarded as a big head. You have to show it and watch your step.
Back when I was a child, we often heard a saying from parents and teachers, be a man first, then do things.
