Managers or Leaders?

With whom do you prefer to work?

I like to work with managers who get their hands dirty to have something done, instead of asking someone to do the work.
Managers that exist to manage people shouldn’t be necessary for mature and autonomous teams.
Think about it. If there’s no one to perform the work, what’s the point of having a people manager? In the end, there’s no one to manage.
On the other hand, if there’s no manager, but the people needed to perform the work are there, it can still happen.
I imagine that people managers won’t like reading this post (if they’re ok being in their comfort zone). But I also think that this should be an opportunity for them to re-invent how they work to be still valuable to their teams.
I prefer to work with leaders instead of managers, people who inspire me.
So, if you’re a people manager, I have one favor to ask you, become a leader and lead by example.
