I have a real concern when staff berate or negatively address a coworker or another absent staff member when they are IN FRONT of pts. It sends a message to the present pt that the facility hires bad employees.
I'm sure that this is NOT a message that the institution wants to convey to the public. In a time when public image and satisfaction scores are carrying so much import, this should not be occurring. I think this would be a issue that higher-uppers might be interested to know. Also it is such a deterrent to team building and cohesiveness.
Now I don't want to sound idealistic blowing glitter snow around, but in all the management and team building seminars I've sat through, rule #1 is DO NOT TEAR DOWN YOUR PEERS in front of others, particularly the public.
I don't kow how receptive OP's higher-uppers might be if she were to somehow broach the subject with them. Maybe somehow dropping a concern thru the Corp hotline? Somehow without dropping too much damning details and finger pointing that could come back to bite OP in the butt.
Sadly, I'll bet there's a group of that level of managlement present who never heard of rule #1.
