If your managers do not understand what they are being told, then they need to bring in an outside expert. The help that you can recieve here is going to be limited to the information that you provide.

If things are as bad as you make them out to be, you really need to have a serious one on one with your manager and make them understand exactly where you are coming from.

If the management is not willing to take your complaints seriously, you may just want to look for new job anyway's.

If any of what you are saying is true it is a disgrace to all of the network administrators that abide by the rules and do not abuse the inherent priveleges that one has due to a title.
