I am in the US and have 35+ days in my package and cannot fathom a situation short of major illness where I will use them all in a calendar year.
I realize that it is cultural and probably due my generation’s reputation for work ethic and disregard for work/life balances. I also have been lucky in that I am rarely sick enough to miss work and being remote just means you power through it (I have lost only a half day to sick time in the last 15 years). I see sick days eating up a lot of my colleagues paid time off.
I think on average I probably take a total of 20 days off a year, broken out as 10 days around Christmas/new years, 5 mid/late summer, then 5 around other holidays to extend a weekend.
Under our enumerated policy, I have 23 days of PTO plus 9 company-chosen holidays plus 5 sick days per year plus a 4-week contiguous sabbatical every 5 years. I have also taken 45 days off in a year under this enumerated policy. It's not unfathomable to take 35-45 days off in a given year. (I'm in the US.)
