It means they cannot schedule time off of work to care for an illness, surgery, etc. It would prompt most to search for other lines of work but, in rural counties, not much else is available.

Living in a rural area is a lifestyle choice and a luxury, and this is simply one of the costs of rural living. There's a reason people lived in larger and larger settlements (villages->towns->cities) starting from the very dawn of civilization, and probably before.
