I have had a few bosses in my 38 years in the work force.
Just in the last 10 years I have had bosses whom I absolutely adored, the best boss I've ever had, the worst boss I'd ever had, a boss with whom a subordinate relationship shouldn't have worked but remarkably did, and a boss whom I consider to be a personal friend. I would suspect that in three decades in management I have been one or all of these to others myself.
At some point in my career I learned to stop fighting the boss. I can tell you exactly when it happened. When the cross-section of professional responsiblity and personal maturity intersected, I realized that I had a duty to support my boss in every way I reasonably could. That sometimes includes telling them when I think they're wrong, and sometimes included stopping by their office to pay them a compliment or provide some other word of encouragement. It damned sure always included telling them when they'd pissed me off, and why. And it always meant that engaging in gossip behind their back was a bad idea. I'm not saying I never did it. I'm saying I profoundly regret it because it absolutely accomplished nothing, and actually set us back and made the boss's job harder.
Look, I'm not the perfect employee - everyone of those boss's listed above would agree on that. I like to believe I have always played full out. What I write here is what I believe, although I was accused by former co-workers of being a self-serving liar and thief the last time I expressed loyalty to my boss.
To them, I invite them to (expletive edited) themselves hard. And have a happy holiday.
Be nice to your boss. It's been a long time since I reported to one who wasn't trying hard.
PS - I used some very rough language up there. Not very deacon of me. I feel a bit bad about that. And.....I'm over it.
