Long working hours, increasingly meager benefits and pay, senior colleagues and supervisors with outdated mindsets, treating newcomers as disposable, or engaging in internal strife and attacking one another, resulting in a high turnover rate among new hires. The environment is poor, especially for on-site personnel who frequently switch between day and night shifts; they are reassigned before their biological clocks have adjusted, which takes a toll on their health. The only advantage is that, as a large company with a well-known brand, employment is stable, and employees are rarely dismissed unless they make a serious mistake.
