When it's not busy, it's very relaxed, and you can have a normal two-day weekend.
The pay is extremely low, and the work is exhausting. You have to move heavy objects and load and unload goods. During the interview, they say that they will accommodate overtime as much as possible but will not force you to work it. In reality, supervisors will follow you to the locker room and ask why you are not working overtime. If you do not work overtime on Saturday, you have to give a reason. The supervisor will write it down in a little notebook and report it to management. Management will require a minimum number of people to work overtime, and at that point, it becomes a contest to see who has the least shame and is willing to force work onto others. The supervisors lack management skills. People who slack off can continue slacking off without being reprimanded because the supervisor says there is no point in scolding them. But if someone who normally works competently slows down—even for just a moment—the supervisor will talk about them as if they have made no contribution at all. It is a deeply disheartening company.
However, the supervisors are not exactly having an easy time either. Excessive overtime is routine, and working more than 12 hours a day is considered normal. They endure what ordinary people cannot, but they also use themselves as the standard and expect everyone to work lots of overtime to help share their workload. Foreign workers have even fewer rights; even if they say they do not want to work overtime that day, they are simply ignored.
The foreign workers' abilities and work ethic vary considerably. Countless people secretly hold outside jobs, whether openly or covertly; they do all kinds of work, and no one has evidence proving that they are working.
In short, it is low pay, lots of work, and close to home. People who just want to get by and those with decent physical stamina can come here.
