Which is more tired, the packer or the assembler?

Because the assembler assembles a finished product, it is to assemble a scattered object into a semi-finished product or finished product, while the assembler in the food industry is more related to loading, so the assembler is tired.

A packer is a person who packages articles with metallic or nonmetallic packaging materials. On July 2, 2020, Ministry of Human Resources and Social Security released 100 jobs in the second quarter of 2020, ranking 10.
