What's interesting is that the nuances don't completely fade out of site. They exist in quiet and sometimes quite intricate underground conversations. I've joined organizations where it was howlingly clear that the official messaging was not the way the company really ran.
That invites the question of whether it's worth staying long enough (and being bold enough) to get drawn into the nuanced underground dialogue, too. Sometimes yes. Sometimes that's quite exciting and makes the job more interesting and more durable.
Other times, it's just too hard to wiggle into that circle. Or that circle has its own evasions and power struggles. In those cases, it's easier to meet the basic formal requirements of the job, enjoy the extra time to have a rich life outside of work -- and think hard about what kind of next job would be better.
