Managing people is absolutely, 100% for at least the last 10 years, being aggressively and successfully being reduced to low skill labor. For example, things like ordering inventory, scheduling staff, pricing products are all done at significantly lower pay rates than were done in the past. The only thing that has slowed some of the automation is simply a shorter route to developing nation outsourcing.

The reason developing countries still dig ditches by hand is because it is still cheaper. The reason for that is not access to automation but the massive wage differential that makes that labor so cheap. Its the low cost of the labor that actually protects it from automation. So therefore it follows that expensive(high and mid skill labor which is even more scalable due to lower material costs since it can typically be automated without machines) will be the most profitable segment to either automate away or reduce to low skill labor.
