There is a lot of IT work that could be outsourced, but not quickly. It would take even highly skilled replacements a year to spin up on that particular system.Maybe maybe not. It depends on what specifically the IT worker does. If it's something like working on servers or AV then yeah they may be in trouble. But for anything that the worker needs not physically be present can be worked around.
Unfortunately senior management tends not to understand that last part. They think all geeks are interchangeable at will.
