I've had flu twice, and both times I simply wouldn't have been able to leave the house no matter how much I wanted to - even just turning over in bed was a major effort!
Would people not have spotted their shivering and sweating and sent them straight home again?
The US has poor employee regulations though, most other well developed nations have figured out people being sick at work doesn't help.
In Australia, full-time employees (38 hours or more a week) will grant you 10 sick days a year. You can use this at effectively any time (Some employers may request medical certificates for consecutive days) but when using it, you are paid your full normal rate for the hours you are away from work for. Once you run out of sick leave, you can then use "unpaid sick leave", which is exactly what you expect.
Shit pay, no benefits, and managers who threaten to fire you if you dont show up. Sick? Puke in the bathroom.
Whys this the case? Cause we Americans have garbage for labor laws. You can be fired for pretty much any reason. And you are NOT protected if youre sick.
When I had to work food seevice, at starbucks, subway, random pizza chain, etc, I begrudgingly came in sick, infected LOADS of customers. My choice was to work, or get fired (or not fired but 0 hours for next 2 weeks on schedule as punishment).
Who knows how many I got sick and potentially killed due to compromised immune systems. Im sure I did.
This is the real, hidden external cost, of our unmitigated capitalism. People get sick and die for the reason of making the boss more money, and too fucking bad.
Divorcing health care from employment would be a wonderful change, but I don't see it ever happening. Employers love it because it makes employees fear for their job, and insurers love it because if everybody saw how much they were actually paying every month they would fight to change the system.
The world is bigger than the US. Also, not everybody in the US is an underpaid service worker with no benefits. Also, if you limit yourself to just the US, you're still just wrong [1]:
> Approximately one-quarter (26%, n = 303/1169) of adults (aged 16–64 years) with self-reported ILI took time off work for their illness for a mean of 3.3 days, compared with 31% (n = 31/99) and 20% (n = 3/15) of those with confirmed influenza A or B, respectively, who reported missing a mean of 3.8 and 3.0 days.
