He is not saying that he "won't" answer the phones or support users.
That was not the impression I got.
The impression I got was that the CIO mandated that user support comes first. And that Everyone needs to pick up the phone.
Now someonecorrect me if I am off base here, but this is why we have tiered support.
Tier1 (helpdesk) picks up the phone and takes the service call. Tier2, support, goes and services the pc. Tier 3 and higher supports tier2 when they can't fix it.
Essentially, I better not get a phone call to install someone's printer. That is not what I do. It's not an attitude thing, it is a clear job function.
Now if for some reason, that system has some really bad problems with it. And the tier2 guy can't fix it. Then by all means he should get me involved. I will guide him so he can fix it.
But Sr IT should not be taking the support calls right off the bat and making it their #1 priority.
This has nothing to do with ego and more with job functions.
My #1 priority has to do with Network Operations and Production Server Maintenance and Security. If something goes wrong there, all user support is off. That's just reality. If the servers go down, the users will no longer have jobs because the company would go out of business.
So the door swings both ways.
I'm not saying though that he should not help out. But making user support his #1 goal in life is a different story.
If I was him, I would get the other senior members together, get their feelings on it. And approach the CIO with their concerns and figure out how they fit into the new support scheme.
