Absolutely.
I can speak both professionally and personally. My grandmother is in one of the care homes that suffered a significant COVID outbreak, and we learned after the fact that they were staffed at pre-pandemic levels, even when there were outbreaks in other care homes in the city.
I have worked in care homes. The pre-pandemic levels are woefully inadequate. The amount of time that staff have to spend with each resident is broken down almost to the millisecond. They are given very little time. There's no time for any crisis or any variation from the routine, which makes staff very stressed. They're not able to perform the task they know they should be doing. This has been an ongoing issue, and I don't think that the staff need to fall from the sky, but I do feel there are long-term care facilities that are chronically understaffed and expect volunteers and family members are going to fill the gaps.
What we saw with COVID was, when the volunteers and family members were no longer able to access the homes, there was a significant crisis already. We should not have to depend on volunteers and family members to be able to care for our older adults properly.
