What’s that saying? People don’t quit their company they quit their manager. I think there’s a lot of truth to that.
Well, a manager being (only) messenger (in this situation) is one of the traits of bad manager, isn't it?
I've been very fortunate to have mostly great managers throughout my 12+ year career, managers that actually care about their staff (as humans, not just fungible resources). In fact, that's why I joined AWS 5.5+ years back, a great manager (plug for @thomas_cantrell). On the flip side, I left because of irreconcilable misalignment with my previous manager.
