Nascar covered just about everything, so there's not much I can add except my sympathies.
I've held this same position in both good AL facilities and bad, and if you don't have great chemistry and teamwork between your director, your staff, and yourself, it makes a decent job difficult, and a difficult job impossible.
FWIW, I think assisted living facilities are all pretty much high-acuity now. We're getting the kind of residents who would have gone directly to nursing homes 15-20 years ago---moderately to severely demented, incontinent of B & B, sliding-scale diabetics, chronic wounds, 2-person transfers and the like. At my building, about the only residents we won't
take are those with feeding tubes, wandering issues, dysphagia, or who need mechanical lifting devices.......and those will be coming in the next 5 or 10 years, I'm sure.
In the meantime, you have to get control of your staff and make them respect you; if they will not accept direction or follow your facility's policies, they need to go. Which means you'll be burning the candle at both ends for many days and nights until you can hire and train new staff, but far better this than for your facility to be in stop-placement because of their shenanigans. I also cannot over-emphasize the necessity for both you and your director to have each other's backs and speak to the workers with a single voice, because lower-level team members are often experts in "staff splitting", meaning they play one supervisor against the other like kids running to Dad for a cookie after Mom says No.
Good luck to you. You are going to need it! And please feel free to come here anytime to vent, ask questions, or cry on our shoulders. Nascar, CapeCodMermaid, and I all have years of LTC management experience; we're here to help.
