OK, Palmy, I'll have to disagree with your intial comment as the quote is
from the section about the types of units in an organisation and I made no claims there about what the organisation did or it's break up or who got paid at what rate.
I'll agree a bit about the salaried people wanting to have their own devices, but disagree about how many of the white collar workers are in a position to make a beneficial use of them unless you let them choose what type of desktop the accounts and secretarial staff want to put on their desk.
I also agree some of the salaried (ie managerial) staff will be working away from their desk, as I stated later in my original post. But I've worked in production facilities, both on the shop floor and in the admin area, and in large admin only type operations (federal public service being one) and the great majority of the white collar workers and even the salaried staff did NOT do any work involving the corporate computer systems away from their desk. Yes they were some, but very few and they had notebooks; even then they mostly used them to review or create documents copied to the hard drive, they didn't do remote access of the corporate systems due to the security not allowing it.
I agree with your assessment it's a very small number of higher level people, which is why I started this sub-thread.
One of the things about this whole BYOD thing that a lot of people seem to be ignoring is that the use of a wireless accessed device being given easy access to the corporate network is virtually the same (security wise) as installing a wireless point with no or little security on it. In the past many senior execs got sacked for doing that to make the sue of their office layout easier for them. Now we have people saying that's the way to go.
It all seems very silly to me. For the senior execs who want easy access to their emails and calendar, as that's about all most need while out of the office, set them up something in Gmail they can access from their desk as well. Then they can anything they want and you don't have to worry about how it interacts with the network as it won't need to.
