What's the difference between a mechanic and a general worker?

There is not much difference between a mechanic and a general worker. Engineers and mechanics overlap, but most mechanics just give ordinary workers a basic salary, and then the so-called mechanics think they are awesome! Painters, auto mechanics, drivers, workshop first article confirmation, line changing, machine debugging and common fault handling are all technicians who guide the general worker's operation methods, but these positions do not require you to be more professional! As long as you are not a fool, you can get started with a little training, and HR is also the resume of a group of fresh graduates, no matter what major you are, you can do it yourself! Good things can be seen at a glance, mainly a proficiency! This is completely different from a product development engineer! Learning technology in foundry enterprises is pure bragging! The gringo's assembly line machine and supporting software make the work stupid! The purpose is only to give consideration to quality and improve efficiency. Technology is made by these equipment and software manufacturers! The highest-level technician in manufacturing industry is a product development engineer!
