as DON/ADON ....do you help or hinder your staff?

I am an LPN in LTC. We got a new DON from out of state 2 yrs ago...who has since made tons of changes that originated from her home state. when she makes a change she says the same thing all the time "Its per corporate"....which half the time is bull. She made up an attendance policy that she herself doesnt adhere to or follow. She is an intelligent nurse...but she has this "i dont care" attitude about staff and residents. she takes it upon herself to cancel residents appointments if she thinks they dont need them....she changes meds and diets if she thinks they arent right. She never helps us with admissions or paperwork or with short staffing issues. She doesnt explain new things...she leaves notes and tells us to sign it. She has made families think that us other nurses are incompetent and that we dont know what we are talking about or doing....not good. She doesnt deal with staff issues such as : constant chronic call ins (its usually the same ones who call in or dont show at all...all the time and still have a job), the lack of teamwork in some nurses and cnas as well....the poor training that new nurses and aides get including sloppy orientation, she tells the day charge nurse to "get out of here" all the time and tells her to pass on her 4 to 5 hours of leftover orders, labs and consults to me (i do charge on 2nd...but i run a cart, tx's, charting, assessments etc) and i dont have time to dotheir work plus mine. The day nurse always gives it to me instead of splitting it...i think that if its going to be passed on...pass on whatever you have to the nurse in charge of that particular pt instead of me all the time. if we end up short on a shift..she or the adon dont help us...they tell us we have to stay over and expect us to be back the next day....the call ins never even get a word said to them...i had to fill out 5 med errors in one night d/t not having meds for 5 diff pts....the pharmacy didnt send them til after 3rd shift was there......she came to me and told me that they were just misplaced...i know they werent there..i checked 4 x before i ever filed a med error sheet on them....what she did was use that as a way to get out of reporting that to corporate in her wkly reports and not only was it a falsification....but it made me look like i overlooked something that absolutely wasnt there....my ? is this..as don / adon...how would you deal with each of these scenarios? do you help your nurses? or leave them hanging?
