PCs may have made some things simpler, but they have also complicated a lot of things. You look at your people. Nobody just sits around. However, all these people could be doing everything but not their jobs. Should you try to spying on them? Or possibly there could be more options around that deal with internet monitoring?
In the past the choice for superiors who wanted some control was limited. Only spyware was available for computer monitoring . Spyware is the name for computer applications that make screenshots, copy text the user inputs into their computer, monitor traffic. With spyware you have more control than you would want. The problem is that you may lose something else. It is not easy to respect and trust people who spy on you.
