Agreed. I'm a big believer in set vacation days. However I think untracked sick and personal days have merit. If you need to go to the dentist or stay home with your kid, do it. Similarly, I like core hours when you're expected to be in (crucial for meeting planning), but still have the flexibility to come in late or leave early.

I interned at Daimler-Benz in Germany. We had a 37.5 hour work week and "flex time" with core hours of 9:30-4:30. My boss made a big deal of explaining that, unless we were at a test track, that we were expected to abide both the core hours and 37.5/week. Core hours were 7hrs/day.

That meant we could work our 30 minutes flex per day in a totally flexible fashion...
