I work in an assisted living facility. The staff all get along great, and we get along with family and visitors and know all the regulars on a first name basis and vice versa. We're held to a pretty high standard, we're one of the silver award recipients in our state, which most facilities don't have. Only 44 out of roughly 300 facilities in my state have it.
The staff, however, is horrible. There are 5 of them - 5 women one guy. They don't say hello when I come in even though one of them has to open the door for me. They don't even offer a casual "how are you?" when I come in; if I ask, they won't reply. Today, they were talking and laughing so loudly when I was playing, I could barely hear myself. I was trained to sing for theater, and play a very good, loud acoustic guitar so I can push some volume. I'm no match for 5 people though. I decided to play my loudest, most abrasive stuff, and stop singing so I wouldn't strain my voice, I also called my contact person to let him know about the issues with the staff.
You're right, that is pretty horrible. We would get in huge trouble if we consistently failed to greet visitors, even regulars, let alone anyone we don't know or recognize. Part of our job is to be warm and inviting, so if somebody is regularly overly shy and aloof from guests our boss will talk to them about it. The problem at the facility in question is not necessarily the staff, but rather the management. Have you complained to the administrator? If the administrator was, for instance, out that day and didn't see the behavior they might want to know. While the cat's away the mice will play, so the saying goes.
I've heard stories about other facilities (and it's always the ones without the silver or gold awards) where staff are rude and inconsiderate. Some of our residents came from those facilities precisely because we don't tolerate that kind of BS in ours.
When I called my contact guy, I started out animated but calm, then kinda escalated into - I'm not sure what you call it. Not unhinged, exactly, but fairly borderline-y wig-out territory, although I remained coherent throughout.
Honestly I don't blame you. Staff was unpardonably rude. We still go about our business despite entertainers, or bible study, or family members who read to the residents, but we try to be respectful and quiet so as not to be disruptive, and we will also redirect disruptive residents so the other residents can enjoy entertainment in peace. If they're being so loud and obnoxious that they drown YOU out then honestly it isn't unreasonable to be angry.
The other issue is that I find this kind of behavior (on the part of the staff) upsetting and hurtful. It's supposed to be fun, not some stupid power-struggle over who can be the most obnoxious. It's also unnecessary for people to be nasty - I'm borderline and I say hello back when someone speaks to me.
The problem is the staff. You probably can't win with them. File a complaint with the administrator and your employer, that's really all you can do. From there it's up to you whether or not you can tolerate rude staff to entertain the residents or if they need to find somebody else to fill that slot.
some of my coworkers had pretty obvious bitterness issues when we had visitors like that.
People like that don't last long at our facility, they get fired. Then they go to other facilities that don't get state awards and complain about what a terrible, neglectful, abusive place we are

.
Try not to take it personally and just focus on those residents, you're likely one of the very few highlights left in their lives.
Can't agree with this more. Most of our residents don't have regular visitors from their own loved ones. Family of OTHER residents will visit with them when they're there, but their own family and friends either stopped coming in a long time ago or never did to begin with. Dementia can be very ugly, especially at first when you don't understand why your intelligent, gregarious, patient, loving father who has always been there for you is suddenly claiming you owe him $20,000 for taking care of your family while you were away in the gulf war, being cruel to his wife, and destroying his relationship with at least one of his children for no rational reason.
People unfortunately often find it difficult to truly comprehend these issues, these changes in personality, stem from a degenerative brain disease slowly destroying their ability to use logic and reason, and eventually their motor function and then vital organs as well. These people often become paranoid, afraid, irrational, and even psychotic. Of the family members who DO understand, many of them simply cannot cope with it and want to remember their vibrant, funny, energetic, selfless mother, not the completely incontinent, gibbering, wheelchair-bound husk she is now, and no longer recognizes her own children.
Most of these people literally have nothing and nobody left. One woman has a granddaughter who visits once or twice a year. Another woman's son comes in to pay her rent 4 months in advance and his checks bounce because he drains her bank accounts and spends all her money before the checks finish processing. She doesn't recognize him and ignores him, and that also visibly distresses him.
It's up to you. The facility will find somebody else to fill that time slot if you don't want to do it anymore. But I do want to mention that you are there to entertain the residents, not the staff, so just ignore the staff. If they are rude again don't hesitate to ask them to keep it down a little. If they continue to be a problem complain to the administrator. If it's a larger chain/franchised facility, complain even higher.
