Given your description, you're the sole sysadmin. This means you're the person who should take these decision - nobody else. If the company disagrees with this, then either you've done a poor job previously, or they don't trust you to do your job for some strange reason.
Now, if it's you that have fscked up on previous occasions, then it's understandable that they want the red tape.
If you haven't, then it's time to put down the foot and say "Nope, that's my job". If they disagree with that - linkedin should be a relatively short distance away, and after you find yourself a new job - simply hand in your resignation pointing out that you have no interest in having babysitters.
