I don’t know if she had a college degree or not, and if she did, what it was in. Most of the admins were in their 20’s and 30’s, and had college degrees. This particular lady was older than I was, so she was of the generation of admins that did not have college degrees. Frankly, her job was not that complicated, and I imagine a technically savvy high schooler could have done it.
This brings up another issue. When I started working 40 years ago, very few admins had college degrees. Now it seems that at a corporate level, a college degree is a necessary requisite for the job.
