You will encounter business decisions you think are terrible but you still have to sell to your team. You cannot vent your frustration to the people you lead.

I actually disagree with this point a lot, as an IC. My manager shares his honest opinions with us, and I respect him more for it. It seems like the rest of the team feels the same.

I’ve had managers try to sell <obviously bad thing> as something good for the team, and it sucks. It feels like being gaslit. I think honest, open communication is a much better way to run a team. We’re all adults and professionals too; we can handle the truth.
