If the cause of mistrust on the part of the management has become some specific error, you need to find solutions to eliminate the consequences of this error. Assess the consequences of mistakes for the bosses, for you personally, for the company you work in. Analyze why you made a mistake, maybe you should ask advice from more experienced colleagues. If you have several solutions, discuss them with your superiors. Explain to him that you understand what was wrong and for what reason. Show the bosses the results of the work on the errors. Ask what he thinks about this. If the cause of distrust to you arose because of your behavior in the team, then it is necessary to change the style of your communication. Do not share with colleagues all their experiences. No matter how good the collective was, there will necessarily be situations when someone will appreciate your actions, your success is inadequate for you.
Your colleagues will certainly share their assessments with their superiors. When you meet the boss outside the office, do not look at him with your faithful eyes. And better let know that you know the reason for distrust towards yourself and are ready to improve the situation. If the boss is too prejudiced against you, you need to talk quietly with him, even better in a joking manner. Help him understand that he treats you more severely than you deserve. Do not start a conversation with the authorities with the words: "What have I done?" This will only aggravate the situation. Start differently: "I know I did a bad job with it" or "I did something bad", "I want to try to make amends for myself". Then suggest the options for correcting the mistake. Somewhere in the middle of a conversation, be sure to ask the boss about your work as a whole, so as not to make a new mistake.
Ask him for advice on correcting the mistake, because he is for you a real professional, and do not descend to banal flattery, because this kind of behavior will only hurt you. Increase your load. See what you can do in addition to the main job. Choose additionally the work that you can do better than all colleagues, while correctly assess their strength. The next your puncture will not only not return the trust of the authorities, but will lead to the fact that you will lose it forever.
If you have at the enterprise, the company has functions that your colleagues do not seek to accomplish, for example, the organization of some events. You should take it up for it, before all this carefully thought out. To show the boss that you are very worried because of an error committed on your part, ask for a punishment. For example, in the form of work on weekends, until you correct the situation. Work on weekends sounds very depressing, but the correct approach to work on the weekends will allow you to have a good rest. Anyway, the majority of the population spend their weekends on a scheme: rest before lunch, watching TV, and all the broadcasts in a row, doing some small household chores, here's the weekend and passed. Of course, I want to sleep on the weekend, watch TV, but we must do everything in moderation. Viewing all the broadcasts on TV not only does not bring you intellectual, spiritual development, but also will not give moral pleasure. Therefore, it is worthwhile to filter the transmissions that look. It is not necessary to watch only scientific programs, it is sometimes more useful to watch a comedy or an entertaining program.
And the work that was taken to the house, it is better to do in the morning, then there will be time for evening rest. If your boss is quick-tempered, but quick-witted in nature, then you risk hearing many things that are not pleasant about your qualities and about yourself, when you mention punishment. But a flash of anger will pass, and career prospects will open again. If, on the contrary, your boss is vindictive, it is worse, since he can remain silent, and then he will remember your sins for a very long time, thus stretching the punishment for an indefinite time. With this type of boss it is better to immediately talk about the problem, and offer for yourself a specific punishment, for a specific time.
The conclusion to all that has been said is this: if there is distrust on the part of the authorities, then it is necessary to discuss the current situation. Do not leave the situation, so that everything will be resolved by itself. That's how difficult the career is, how to regain the trust of the boss, you know. I wish you success!
