It's definitely done. A traditional method is that the longer you've been at a place, the more vacation you earn. Another technique I've seen is to have a divide, eg "VP and above get an extra 5 days per year."

Facebook, Google, etc commonly use the contractor technique, where anyone you want to work for you but not give benefits becomes an independent contractor, or works for a vendor. Eg, the cooks in the Facebook kitchens.

Yeah - I've seen tiered vacation days based on seniority, but I'm wondering specifically about giving some folks unlimited and others a prescribed number of days. That seems to straddle an almost philosophical issue.
