@LM Your story reminded me of one of my own. The worse years of my working life were in management, but it did have one worthwhile side effect. When I was out I would tell a manager of some problem that I knew he/she didn't want to hear about, but always added the caveat, 'When I was in management I would have wanted to know about this kind of problem". That was a complete lie, of course, but no manager couldn't openly say that he didn't give a rat. A minor pleasure.
I once worked diligently on a project which involved getting feedback from clients and writing recommendations. I gave the report to my boss, and soon the clients started calling her to ask when the recommendations were going to be implemented. She called me into her office and asked why I had done this without her permission and was upset that this had caused the clients to bother her. I reminded her that she had told me to do it, and even given me information and past recommendations for input. She said, "But I didn't think you would do it!" Sort of the flip side of Wally.
