When do people listen to you? (Job Series): 34

 

(Photo source: pexels.com)

Have you observed that people do not listen to you when you say something? Why does it happen? It is because either you do not matter to them or your power is in decline. It is hard to digest, but it is true. Some can see it and change their course. It is the part and parcel of life. You cannot be relevant all the time, and the power goes away eventually. As a new employee, you will not have it immediately. After some time, you will have something. It takes time.   

Well, people are smart. They sniff everything to the core. Once they assess that things are not right with you, they start jumping ship. People shift their way and adjust themselves as the situation evolves. You too did it so. Now, it is your time to face. People will come and go. Keeping sanity and integrity are the main issues. Face the situation like a man. Things go wrong, and they become okay after some time. It is how it is. Like everyone else, you will develop thick skin and move on. It is always like this. There is no point in being sour. At least, you will be able to identify the people in this process.

Whenever you have something, it is like people come running. Continuing in a humble manner or a measured approach through such sloppy waters helps to transition to a new phase. At the end, you must live in society amongst the wretched ones and betrayers.

Not in team!!! (Job Series): 33

(Photo source: pexels.com)

Not in the team sounds great because it means less work. On the contrary, you may be missing an opportunity.  

Most of the time, you are called for mundane work. You contribute and move on. It is the pedestal to land in something big in future. You are progressing slowly by contributing something at a time. During those interactions, people will create an image of you. How do you approach work? How do you solve a problem? Are you approachable? Do you have management skills? Can you get along with people?

If you are an average person, you will continue to move steadily forward. On the other hand, some people are extremely difficult to manage and unreliable; they will be pushed aside. It is like nature choosing the fittest in the process of selection. 

Now, who are these people getting shunned? Some people talk a lot, but do nothing. People need doers, not talkers. Talkers are available in thousands. Whenever you approach such a person, you will hear long talks. People like the ones who actively participate. Work life is all about give and take. Well, I am saying it in a good sense. One should not take it otherwise. You give someone some time; you will reap something good in future. At the worst, you will have some learning. 

While gathering a team for something important, you will be remembered. Due to your active participation in previous assignments, you will be roped in. This is going to be your juicy part of the affair, which will take you closer to something big. Before getting to do big things, you do lots of simple, mundane tasks.  

Reliability is another characteristic that should be maintained during work life. Workplace works on the principle of reliability and hence, predictability. No one likes to have surprises. Your reliability saves everyone. You should understand that in workplaces, people do things in a disciplined manner. When you bring chaos, the whole process gets derailed. 

It hampers others’ personal lives also. People may have other engagements after office hours. Due to your unreliability or indiscipline behaviour, others miss their engagements or leave home with stress. Over time, it accumulates, and people will gang up and push you to the corner. Therefore, one should not rock the system so violently that people just have had enough of you. 

When you are in a team, you should not be someone who is backbiting everyone. It will bite you someday. Everyone can see whether someone is contributing or not. It should not be you all the time bringing it to everyone’s attention. It leaves a negative impression if you overdo it. Our lives are largely filled with such people around us. More importantly, you make lots of enemies.
