The companies compete for workers, especially highly skilled ones. One company rising wages would push others to react in a similar way assuming they compete for the same talent.
I was referring to the WFH aspect the parent post mentioned. My point was that the admins could get the same level of access as if they were physically on site, assuming the correct setup.
It is a matter of preparation. You can make sure there are KVMoIPs or other OOB technologies available on site to allow direct access from a remote location. In the worst case technician has to know how to connect the OOB device or press a power button ;)
