It is absolutely necessary to have a work-related injury appraisal, in order to safeguard one's rights. According to what you said about his injury, I think he may be disabled at level 7. The unit only paid him medical expenses, which is what they should do and only a small part of what your friend deserves. Because the company didn't buy work-related injury insurance, all work-related injury compensation needs to be borne by the company, so they don't agree to identify the disability level, but you can go by yourself, hurry up and don't delay.

According to the compensation standard of the Industrial Injury Ordinance, your friend can get the following expenses:

1, medical expenses 2, lost time 3, food expenses 4, nursing expenses 5, disability appraisal expenses and travel expenses 6, one-time disability compensation 7, one-time medical compensation 8, one-time employment compensation 9, nutrition expenses 10, and other mental compensation.

Of these 10 items, items 6, 7 and 8 are the most important, and item 9 and 10 are not clearly stipulated in the law, but you can ask the unit for appropriate compensation.

With such a heavy injury, I suggest you do a disability appraisal at once. It's not about thousands of dollars, it's about hundreds of thousands of dollars. For a migrant worker, the hard-earned money earned by his health must not be swallowed up by those heartless bosses.
