Same here.
I've said a few times over the years of how I used to like coming to work before email and cellphones. Email has enabled the lazy and entitled folks to shamelessly forward tasks on those who can FFO and get things done. When you have multiple people doing that in a company, it can burn you out.
I specifically remember around late 1999 a significant change in middle and upper management demeanor. They got nastier, pushed tasks on others (see above), created fake crisis urgency, and used fear like it was the soviet union all over again. I used to say, that I thought some asshole wrote a book on how to manage like an asshole and every ladder climber read it.
Well, it turns out I was right. late 1998 the 48 Laws of Power came out and by 1999 Havard biz school was pushing it. All the management wannabees read it and enjoyed treating coworkers like shit to get ahead. I heard of this book about 10 years ago and read it. Immediately, I realized it was all a fake BS power play and these people gave up on their integrity and humility in order to try to make themselves look good by making others look bad.
