Comes from the LeadDev.

A good overview of the myths about "managing up". The "why" behind the "whats" is to be an individual who helps foster a stable and productive environment for their colleagues/reports.

Quotables:

Forget about the notion that it’s “not on you” to accommodate a supposedly more skillful boss. They have different skills from you. They may even be less skilled than you. Your moral outrage at the situation is not useful. If you have a boss, managing up is part of your job.

The lead who is not great at managing up is also less able to sponsor others, a less useful ally to their own team, and their team has to contend with a harsher broader environment.

There's good case study stories in there, quite informative!
