Tessitura for HR, Staffing, etc

We're starting to explore creating (or, better yet, discovering!) a solution for using Tessitura for some HR purposes: copies of contracts; vacation accrual, requests, & usage; and ticket allotments. We already use relationships and constituencies for basic staff tracking, but that's pretty much it.

I know there are a million ways to do this-- and have seen a number of different posts on everything from web-based volunteer portals for tracking hours, to creating dummy maps to track ticket allotments and scheduling.

Since we're starting from scratch, my first priority is to make sure it works for our needs but, wherever possible, I'd also like to use existing standard functionality (although perhaps in a non-standard way), both for ease of implementation, and for continued use.

So-- who IS using Tessitura for HR & staff purposes? Or artists, volunteers, etc? What are you doing and would you recommend it? Are you using custom screens or something standard?

Thanks!
