It's completely dependent on the job, and that's a problem. Good jobs offer ample time off, bad jobs offer the bare legal minimum. Unfortunately the legal minimum is really oppressive and causes a lot of people to go into work sick, getting everyone else sick in the process.

I think the idea is that you're actually sick for a week, not "sick". And can't show them anything until you're better. If you've ever been that sick, you know you can barely get out of bed to go to the bathroom.

Edit: Sorry about this comment, it's pretty useless, I just had time to kill waiting for my next flight. Reads like a fictional dystopian exaggeration, but it was my reality and continues to be reality for many others, unfortunately. TL;DR - anecdotes outlining how US working conditions can be brutally unforgiving, especially in the restaurant industry.

There's 3 days sick leave in the US? When I was still living there, I got my 2nd write-up (3rd = termination) for not coming to work because I needed to go to the ER for an overdose. Side note: caffeine powder is way cheaper than coffee, but if you're too broke to afford coffee, you're too broke to afford a milligram scale reliable and accurate enough to prevent accidental overdose.

After breaking my 30+ day streak of 12-15 hour shifts (about 90-100 hours per week, was normally only 85 or so), I came back to work the next day with a doctor's note, and my boss said "I don't think you're lying to me..." followed by 10 very long seconds of suspicious squinting and staring me down, "... But yesterday was Saturday, so I'm going to need to write you up". You see, it was explicitly forbidden to call in sick on a Friday, Saturday, or Sunday.

Don't let your loved ones work in restaurants, ESPECIALLY in the kitchen. I unfortunately couldn't quit because I had no days off to apply for other jobs, and missing out on even one day of pay was the difference between covering bills AND food, or having to steal food to avoid homelessness. I legitimately considered choosing to be homeless temporarily as a way out, because I pretty much lived at work anyway, I only ever slept at the apartment. Granted, my situation was particularly bad because they were actually stealing 50% of my earned wages (~$8300 over 10 months, which I eventually got back after threats of litigation).
