So, I can now say I've worked on both sides of the fence (private and gov,) and run into people and managers that fit the editorial to a T.
I didn't read the OSS manual, but in private industry I've had a boss who regularly gave me a hard time, while praising others. Worst was when such issues would then get raised on "annual" reviews. "Oh, you put in a couple Saturdays to do this thing my boss wanted us to do (re-organizing and neatening up the server racks,) I expected you to do this, you get a "average" rating for this." Yeah, real demoralizing.
Now that I'm in gov, the never-ending meetings are real. Meetings that the most I have to input sometimes is "I'm here" with the teleconferences. At least when we have in-person meetings (pre-COVID) the bosses could look at the agenda and tell me "yeah, we're set with you for now, if we need anything else we'll come get you," and let me get on with my day.
