Not particularly directed at you, but it's certainly a dichotomy in that managers are the only ones responsible for "rethinking another's employment". I'm curious to know how often you would consider reflecting on / rethinking your own employment?
I say this because I was recently hired to work on a project where managers are obviously the only ones responsible for deciding how a developer should function within the organization. It is obvious the state of the project is anything but healthy at the moment. Attrition rates are astronomical and the code is beyond ugly in a lot of cases.
