Ok, guys current SKW guys, what's the deal with benefits?

My wife just came down with pneumonia, and she's getting treated, but I start class on Monday. We live in NYC so coming home is not too easy from SLC.

But when are medical benefits active?
Also, does the employee have immediate non-rev benefits, are you put in CASS off the bat or wait until after training? I'm curious because I may have to come back on the weekend, and if she needs to see the doctor, what benefits do we have as a new hire.

Thx guys.
