from https://www.bls.gov/emp/documentation/nem-definitions.htm https://www.bls.gov/emp/documentation/nem-definitions.htm: No formal educational credential. This category signifies that a formal credential issued by an educational institution, such as a high school diploma or postsecondary certificate, is not typically needed for entry into the occupation. Examples of occupations in this category include janitors and cleaners, cashiers, and agricultural equipment operators. I didn't look to see if garbage workers specifically get higher salaries, but could be. But even if that's the case, it doesn't seem like a very high salary, so, assuming that unions are not in a zero-sum game, and didn't need to cause other salaries to lower, this sounds like a benefit of unions. Or is it a drawback? I wasn't sure how your statement was taken.
