I was a network administrator at a site, which just made me a glorified system admin with responsibility for the network and switches.
Everyone in the IT Dept had the password for the switches. After one person gave a 3rd party vendor the password, I had to change the passwords and exclude him from having it… but then everyone else got the password.
That place was nuts, between that and a few other stupid boss actions, I just moved on. Found a much better job and it was for the best.
