How about elevator maintenance? Is it dangerous?

I'm a maintenance worker. If I follow the rules, I have to do too much. An elevator should be maintained twice a month, once every six months and once a year. The specific tasks are all on the list. You will know when you come. Just like your classmates, they all went through the motions and didn't follow the formal requirements at all. But this is also the status quo of this industry. The maintenance premium of an elevator has dropped from seven or eight hundred to two or three hundred, and the maintenance company still has to live. As a result of reducing costs, the quality of service is also reduced in disguise. The elevators sold by the elevator production company are basically not maintained after the warranty period, and they are all taken away by the small maintenance company, which is vicious competition. Elevator maintenance is dangerous. First, it works at high altitude. Second, it involves touching 380V high voltage electricity. However, it can also exercise a person's endurance. Your classmate's situation should be a new elevator with a single brand. This kind of fault is generally low, so I feel fine all day. If you come across an inferior brand, an old elevator, that phone call called repair can make you collapse all day. This job is available 24 hours a day. Think about the feeling that you just ate with a bowl and the phone came, and you had to put down the bowl to repair the elevator? If you are late, the customer will make trouble for you. If you are a novice, all you have to do is clean and understand the basics. You'll get it. The key is to have someone to take you and get you into the state quickly. Of course, it depends on your personal nature. If you have the ability to understand all this, then you are a real technician. If one day you sit at home to work and others can't get it, you can go again. This is freedom. The boss dare not talk about you, because you are a technical talent. Let me talk about the income of this industry first. There are about 3,000 ordinary skilled workers, and some people engage in contracting, that is, one person is responsible for multiple elevators, and more work is more rewarding, but that kind is also to repair elevators, and another kind is technical support, and you don't have to go to work for one day. If the next one can't be repaired, he will leave. This kind of person just gets an annual salary,100000 or so. Personally, if you have other ways, don't enter this industry. Hope to adopt, thank you.
