In my 20+ year career I only recall working at one place that provided paid sick leave, and that company only provided two weeks of annual vacation. Even if everyone worked from home the full 2-3 weeks they were feeling the least bit off from a cold, the office would be a ghost town for at least 2-3 months out of the year. Which maybe it should be, but that would clearly defy the common expectations of the world pre-COVID.
