It varies tremendously from company to company. 10 days is not unheard of, but for example at my job, new employees get 12 vacation days plus 15 holidays. I've been there 9 years and get 21 vacation days a year plus the same 15 holidays (my long-tenured coworkers and I often struggle to use all of our vacation; we tend to take a lot of Fridays off to stay under the six-week cap). By contrast, many low-wage jobs get no paid vacation.
