The thing is, when you’re in this line of work, it is repetitive. One gets bored after doing the same mechanical thing over and over again. As time withers, you will reach a point where you will breathlessly wait for the next paycheck and not actually care about the job. It’s emotionally exhausting. Furthermore, programming and operating these machines can be tedious. So, add that up to boredom and you get disproductivity.
Another thing that you should think about is the work environment. You’re going to be working in a factory. And factories are located away from town. If you’re not comfortable with being away from the hustle and bustle of the city, this might not be for you.
It can get pretty dangerous. Reports show that although most CNC operators work in a well-lit and smoothly ventilated environment, the high-power machinery poses dangers for them in the form of flying particles of metal and plastic. Also, though most modern machines produce less noise, ear plugs are still recommended by experts.
Lastly, this may not sound like a biggie, but most CNC operators are on their feet all day. They can only sit when the programs are being loaded into the computer. It’s pretty comforting that they receive salaries waaaay bigger than those salesladies.
