What I've noticed is that management have lost respect for their work force. When the time comes to downsize someone they become a post or a role and not a person. If you know anything that is remotely hard to duplicate in the company you are a "silo". Not only is that something bad, but now it is your faultnd you are viewed as a risk. You cease to be a person and are now a thing like those pepperpots the armchair generals move around their imaginary battlefields.
