<human>: and I'd be surprised if that rate of change lets up anytime soon.  

I've had 3 really good bosses and they all shared the following:

*  They allowed me to do my job and only involved themselves when I needed aircover

*  They gave me all the public credit when things worked well

*  The accepted fault themselves when things didn't work out

*  They all encouraged me to grow, develop, and "leave the nest

I've had two awful bosses and they both:

*   Set their employees up for failure

*  Blamed their employees for everything

*  Took all the credit when things went well

The remaining 13 bosses all fell in the middle.  With this kind of change, I've had to learn how to manage my managers, how to advocate for what I believed was right.  And most importantly, how to get them to support my career even after they moved on.

The simple fact is; Gen X and Millenials don't stay tied down very long and if you want to grow your own career you can't rely on your boss to do so, even the good ones.  You have to do it yourself.

Condense the text into a few key points
<bot>: I reflected on the number of bosses I've had then got a little preachy at the end but I'm leaving it.
