She is fine, she is on vacation. It is a common practice at the end of a sweeps period for many anchors to take off because they are not allowed to take off in February, May, July and November so it condenses when they can be off to just 8 months rather than 12.
I am not disputing anything you said, I am just doing to dissect some of it.
"She is not required to report from the field" Not many anchors are though. The only time most of the anchors do, is when there is a big news even like Newtown, Lori Stokes was live the next morning from Newtown. Tom Llamas, Rob Schmitt and the other few are a select few and those are special circumstances.
"has limited fill-in requirements" She is the lead fill-in for Sade Baderinwa and often fills in for Liz Cho. This was at her request though.
Besides that, everything else you said is pretty straight forward. You gain a good salary, paid benefits and vacations as you gain seniority which she has certainly earned by now. She is New York's Katie Couric -- New York's Sweetheart.
