Just follow the rules. It's that simple.
I'm a carer in a nursing home so a bit of a different experience to an ITU or covid hospital ward (even though a lot of hospital wards aren't any more at risk than our home).
But with regards to "what can we do" we'd really like it if instead of clapping, our residents families could be a bit more patient with us instead of getting shitty, with regards to stuff like Zoom calls. Yes we know it's hard for you not to have direct contact with your families (we're also not seeing ours, to protect your family member as well as us), but we are not technicians. If the connection is shit, it's not our fault, we're doing our best. We have a visitor pod but if your family member has dementia/is usually nurses in bed so not used to sitting out in communal areas, and isn't happy to sit there, we can't do much other than encourage them.
We also don't have the time to sit next to them for an hour to make sure they sit there while you get your photos for the gram. We have a lot of other residents and need to get on with personal care/drinks/food/restocking gloves etc.
The families who have sent letters of appreciation/treats/talked about how much we're doing when you're in the local area, we Thankyou. Most of you have supported us and vocalised how grateful you are that your relative is safe and getting the best care possible. Stuff like that goes a long way with staff morale when we're decked out in full PPE for 12 hours and rethink having a drink (because mask changes getting old...).
And if you could vote for a better option next election, also great.
