That said, when it comes to having an ESFJ boss, there's a slightly more complex process. If they announced they are and ESFJ (highly unlikely), that might just make me extra cautious, because unlike my best friend, they are in position of power over me and can very easily make my life very unpleasant. Most likely the reason I'd decide my boss is an ESFJ is if I detect the behavior that I (perhaps erroneously) associate with ESFJs, the "aggressive enforcement of [narrow-minded] social conventions". And in the latter case I would be justified in running the other way because I don't exactly fit into many social conventions. Even then, it's a precaution because technically, no matter how my boss feels about when I wake up in the morning or the means of transportation I use to get to work or any other aspect of my personal life, important or trivial, standards of professional behavior should at least keep them from letting their personal opinions influence their treatment of me at the workplace. But professional or not, I wouldn't feel very safe when someone who doesn't like me has tangible and personal power over me.
You're entitled to dislike whoever you want, of course, but I'm not sure why you're bothering to correlate ESFJ directly with "aggressive enforcement of [narrow-minded] social conventions" when ESFJ does not always correlate with "aggressive enforcement of [narrow-minded] social conventions". Why not just look for "aggressive enforcement of [narrow-minded] social conventions" and skip the ESFJ label all together?
I think it would be far more accurate to say ExFJ preferences correlate with tendency to modify behavior, and SJ preferences tend to correlate with awareness of cultural norms. An ESFJ actually can be a huge asset to someone who does not fit into many social conventions because ESFJs are typically natively good at
navigating within social conventions. My ESFJ mom is a special education teacher, for example, and spends a huge amount of her time working to empower people who aren't good at "fitting in". She doesn't like leadership positions, but when she is in one, she stresses democracy, harmony, and everyone being included and happy. It's funny because she's very Je but she's not an "enforcer" at all, much less aggressive. I wouldn't say she's a great leader, but that's because she's not harsh
enough. It's actually the exact opposite of what you're describing. IMO she's too gentle and accepting when she's in a leadership position. And on the flip side, I know other ESFJs who are great leaders.
And of course this is not all to say that you might not experience difficulty in general with ESFJ types in leadership positions, but it may well have something to do with the way you tend to think in concert with the way they tend to think that creates the clash. I don't think it's just ESFJ + leadership that creates a bad combination. Maybe it is a bad combination for you personally, but I don't think it's an objective pattern in the world at large.
