Oh I'm all for 3rd party oversight, but what it sounds like is this is one of those outsourced HR teams from overseas that are more or less paperwork pushers. They're commonly used to avoid having to pay for actual HR that, you know, actually does human relations. These are separate from 3rd party oversights, which usually are separate from a full HR team.

They usually provide super super duper helpful 1-800 numbers where you, as an employee, can call and complain about something, feel better, gets logged in a report, and nothing then is done. I did work for consulting companies that used these and shockingly, they are terrible.
