Are the packers in the coffee factory hard?

Thanks for your hard work. The job of a packer in a coffee factory requires standing for a long time and maintaining a high degree of concentration. It needs to package and box coffee according to specific requirements. Repeated work for a long time will make the body feel tired. Secondly, the workload of the coffee factory is large, and the packers need to work overtime, which will further increase the workload, so the packers in the coffee factory are hard.
