I so often see people working in IT fail to take advantage of all the tools we have to automate much of their jobs. They often tell me if they automate too much of their jobs, they won't be needed and may get let go.
I've automated much of my job, but by doing so my workload and responsibility grows much faster than my salary or respect. And when automation needs to be modified due to changes in requirements, I have less time, since I'm responsible for 10 times the number of projects I was a few years ago...
