@1qsb+1iwCHpYY - I think I solved your riddle. The safe area that has nothing to do with business success but rather business failure must be the IT Security Group.
They seem to be able to do anything they want, with no notice. Take away your access. Change rules for getting access. Take away your access to gmail and certain internet sites.
All they have to do is say "it's for security" and no one can do anything.
I saw a recent post where people can't receive secure email from customers that they used to receive because it requires being able to access a web site that is marked as "email" an shut down.
Oh, sure, they'll eventually get access, but not until they convene a tribunal and write a b.s. "finding".
To get more people or more money, all the security group has to do is paint a picture of what horrible things could happen if they don't.
But, they never count the cost of their "work" on the common employee just trying to get its job done.
So, yeah, the answer to the riddle must be security.
Do I win?
