We have a PTO structure for our 145 employees, and they are able to roll over 1 week per year - remainder is paid out at end of year if not used.
I myself have unlimited PTO , most I've ever used in a year is 3 + weeks....+ meaning a day here or there I'll tack on to work trips. We went on a 2 week vacation this past fall which was the longest we've every been gone. I was a wreck being gone from work that long - but it worked out ok! No plans for another long trip in 2026 (although never say never - 2026 hasn't even started yet so we will see), just week long trips, so far one in Feb. & one in the fall.
We also give all of our employees paid off Christmas Eve - New Years Day. Glad to be able to do that, and no one has to use their PTO towards it - Company picks it up. A lot of folks will use a few days here or there around the holidays to round out their time off for quite a long stretch of time off.
