From my perspective, the worst job is being a package line worker.
- The job is repetitive, and do not require many specific skills. Therefore the workers might have low motivation since the tasks are boring.
- There is a blurred career promotion path. The chance of getting promoted is very small since the majority of manufacturing corporates often have a wide span of control, therefore some ambitious workers might feel demotivated.
- There is a potential risk of the quality issue which depends on the method a company chooses to pay its workers. If a company is paying its workers at a piece rate, workers might focus on how to get things done quickly in order to get more money, and they might ignore the quality of the products. If a company is paying its worker at a wage, workers might be unmotivated and have low productivity since no matter how many units they produce, they still get the same salary.
