1, repetitive work: On the assembly line, employees need to do the same work repeatedly, which leads to physical fatigue and discomfort. Especially some jobs that need to keep the same posture for a long time are more likely to lead to muscle fatigue.
2. High work intensity: In order to meet the production demand, the work on the assembly line often needs to be completed within a certain period of time. This requires employees to complete a lot of tasks in a short time, which increases the work intensity and pressure.
3. Mental stress: assembly line operation usually requires employees to maintain a high degree of concentration, because once something goes wrong, it will affect the whole production process. This high-intensity working environment will cause certain pressure on employees' psychology and lead to mental fatigue.
