I have worked for more than 30 years, and I don't know if you recognize the experience!
No matter what unit you work in, remember, work is just work, and don't let it affect your emotions. Get along with colleagues, be harmonious if you can, and don't force yourself if you can't be harmonious. Just keep basic politeness and respect.
Leaders only work here, and there is no need to be overly humble with leaders. Respect is necessary, but it doesn't have to be overly flattering. We work for the company, and the company pays us salaries, and it's a mutually beneficial relationship. We don't owe anything to the company.
No matter how busy you are at work, you should also arrange your time wisely and don't forget that you still have a life and a family. Do a good job of time management and don't complain about your salary or situation because no one wants you better than him.
At work, don't get into trouble with your colleagues. They don't deserve your emotions to be wasted. You're just working, don't care too much about what your colleagues and leaders think. If you care too much, you lose. At work, as long as you are worthy of your conscience, you can do your job well.
If you feel tired, take a break. The work is never done. Remember, you are just an ordinary person, live well and care for your family and yourself. In the unit, you are just a brick, but at home, you will always be a piece of the family.
