My son in law had such people under him to help get the work done.

I had a couple of supervisors like that. Constantly had to explain to them simple everyday words and terms. One went two weeks not understanding “cistern” wasn’t “sister” and another always pronounced “perpetrator” as “pepper traitor”, sigh. Their reports were in Ebonics and the secretary refused to tidy up their grammar.
