Angela, thanks for your comment. Do you have influence with this person? Is there trust in that relationship?  Are you a high performer for that individual?  If so, "Leading up"  is your best bet.  Pull the person aside, preferably off site over a casual lunch, and express your feelings without judgment. If you don't have that luxury, it may not be up to you to  initiate. HR  should have leadership assessments in place hopefully in low morale  environments  to begin some performance management.

 I would be curious what other leadership experts in this community would have to say.

Hang in there and please send me a personal message through my contact page if you want more options.  I'd be glad to help.
