I suspect it is more company/occupation specific. High paying white collar workers are probably much more likely to be able to stay home. Low pay workers, likely have much less vacation benefits and all and must come to work. Me specifically I have over enough PTO with no prior vacation commitments that a week off it not a problem.

"High paying white collar workers" or even mediocre paid white collar workers are more likely to be working from home when sick.

I have never had a job where I felt comfortable and able to take a sick day because I had "just" a cold, but since I've had an office job where working from home was allowed, I would also not feel comfortable coming into the office sick.
