I'm not referring to jobs that require complex automation systems, but jobs that just... Aren't needed for a company to function. No consultant needed, no outsourced labor needed. A simple example would be the receptionist at a non-customer facing business. At least where I work, we have zero walk-ins and maybe 5 phone calls a day. We pay someone well above minimum wage to simply answer to phone - despite our VOIP provider offering (for free) an automated system to route calls.
