2 weeks total over a year? Doesn’t seem unreasonable to me. I’ve never actually used that much sick leave myself, but I have it if I need it. Doesn’t seem crazy to me that everybody have the same benefit (or, we could just be reasonable and not actually have sick leave and just let people stay home).
Some jobs coughing and whatnot is frowned upon.
I bet there's things you've heard of in the south that i've never heard of, too.
I'd guess for an average person aged 40 to 60, two consecutive weeks off would be a one in maybe five years kind of event. Any minor surgery, mental health, cancer treatment, heart issue or significant infection like shingles, pneumonia, mono, hep could easily lead to two weeks off.
Two weeks definitely isn't an every year thing for most people but it's certainly not extreme.
