There is industry saturation in the workplace, but it is not always saturated, because there will always be a day when workers retire. Once a worker retires, it means that this industry has a position again, and at this time he is also in an unsaturated state, so no industry is always saturated, and no occupation will never be unemployed, because when you enter this industry, he looks at your personality and attitude towards work.

If you want to find a job that will never be out of date, I don't think you need to consider it, because no matter what job it is, it depends on your work level. If this major is really just being implemented forever, but your major is wrong, it is useless for you to like it again. If you want a job, it depends on which job can highlight your ability and show your talent, because only in this way can you go further.

There are some professions that he will never be out of date, but he is relatively unpopular. For example, one of my classmates chose an undertaker when he chose a major in college, just to make up for his death. This major is actually scary at first, but it will never go out of date, because our teacher also said at that time that if his relatives died, he would die in disgrace, no matter how much it cost.

No matter what job you do, we should treat it with care. If you don't care, your boss can tell at a glance. Sometimes even if your work quality is not strong, but your attitude is very correct, you will not lose this job.

The above is my opinion, I hope it will help you.
