For what it's worth (sample size of 1 - me) - if you are at all competent and bad at setting boundaries, the dysfunction will absolutely frustrate the heck out of you.

Seeing what is broken, knowing that it can be fixed, and having even the slightest bit of motivation or knowledge of how to do so, and how it goes on forever and ever and doesn't get fixed becomes incredibly tiring.

I suppose, if you go into a dysfunctional company hoping to "coast", just be aware, if you are not good at managing boundaries and passing off the "frustration", it might be a lot worse than you realize.

Just imagine.. if you are spending 8 hours a day, 5 days a week, watching a slow motion wreck.. and powerless to do anything about it... sure, you get paid, but is it worth spending the time?
