I cannot say this too often - not only from a team leading perspective, but also from a good friend one!
I joined in freshly, they taught me - I taught them! Together we improved day by day! Almost 10 yrs later, the team is still the same - no one left. I think I can say that everyone enjoys the work and everyone is doing a really great job! I really love this team and it works out that well because we're:
honouring, understanding, trusting & respecting each other!
This is not only about "happy posting" etc. - it's more about also getting taught. It does not automatically mean that a teamlead is always right. It does not mean that this person is always choosing the right path. And it is really good and important that everyone can take the opportunity without any fear to talk about any concerns. This should always be taken seriously, no one can know everything and no one is always right! What did I say in my first sentence - they taught me! And yes, this was the first thing what happened. They taught me!
But what is my hope? I had two really (and I mean it this way) good mentors. I hope, I can be the same for other ones. Helping to improve, to become better... But everyone is special in its own way and needs to treated that way. Hopefully, I can find the right directions...
