Unfortunately the Menninger of today is not the Menninger of Topeka, KS. They burn through social workers faster than switching TV channels, so you will always see them advertising for positions. (Most SW's in the community who have worked there can't be lured back.)
Unfortunately social work leadership is too invested in not ruffling the feathers of the higher ups to really make any meaningful change. The turnover rate is proof - go along, get along.
While lip service is given to supporting professional growth, in truth social workers do the bulk of the clinical work, psychologists and MD's do the "intellectual" work.
With that said, its one of the few places that takes psychodynamic theory seriously. So good place to work for a SHORT time for learning and then move on. That's what they expect from their management model anyway, because they are happy to burn you out and let you go. This is not a place that values cultivating social work talent and integrating it as part of the organization.
