I worked in a group managing well over 1000 Unix (mostly Sun) workstations and a couple of dozen large servers. our days consisted primarily of user "whack-a-mole" operations, fixing stupid user errors, shutting down rogue users and managing break-fix. We (all 4 of us) were constantly exhausted working 60 hour weeks and management refused to hire any additional headcount. We got together and decided to automate the management of all the systems. We locked down all the workstations and made them rootless, booting over NFS. We then added scripts automating the build and rebuild of individual and groups of systems. When done, we'd reduced out workload by 50%. The result of all this hard work was our management trumpeting that we had just been lazy before and we actually needed fewer, not more headcount. I left, leaving the other 3 to fend for themselves. When last seen, there was a single guy working 60+ hours a week. Some things never change.
