Switching care during coronavirus?

I’d keep things as they are. One caregiver can’t do it all. You going on the weekends is equal to having the current caregiver. Your father needs the help, and there’s no perfect way to keep all risk away. Keep emphasizing the importance of hygiene and sanitizing, and hopefully all will be well

Does this mean Dad is going to be alone on the weekend? Because, your can't work someone 24/7.

You could keep one on (if that person wants it) and continue to pay the other just the same so that when things go back to normal you will hopefully still have both. But there's no guarantee the "furloughed" one will come back to work and then you're out that money. I think if you really really like and trust both of them I'd do whatever it takes to keep them.
