>For some people, the truly exciting work is the work where none of this stuff has been proceduralized. It's not feasible to train or do knowledge transfer between two shifts for these projects.

This is true, but this is really question about compensation, not work time. Executives are basically always on call but they get executive pay.

If you are not well compensated for doing the work that can't be replaced, you are being exploited.

Executives also usually have someone filter their calls, their phone numbers are rarely available to random clients.
