NorCal = @20yrs 5 vacation weeks + 2 option weeks + 9 sick days. @25yrs 6 vacation weeks + 2 option weeks +9 sick days. @30yrs 7 vacation weeks + 2 option weeks + 9 sick days.
Option weeks are called Option A and Option B. Option A week is either you use the week as vacation, or you cash it in $$. Option B week is 2 floating holidays, birthday and day after and they add a bonus day off for using it as a one week vacation. Otherwise you can take the floating holidays whenever you wish, and you get your birthday and day after off, but don't get the extra day.
I never once cashed in one of my option weeks. I retired using 9 weeks of vacation a year. I took a week a month off from March through November.
