Not only that (the classic scum bag insurance company "deny deny deny" tactic) but when they play denial mode with this, its our jobs that are on the line.

Once you cross any of the thresholds, which 20-30% of the pilot group will do in any given year, you better hope the underlying condition is "verifiable" to a potentially hostile third party. Get a horrible flu with a high fever? You got lucky, because anyone can verify that. Feel nautious or have a headache or just ache all over with no other "verifiable" symptoms? "Patient claims XYZ, could not comfirn nor deny". Is that going to be enough to save your career? You willing to bet your career on that, every illness for the rest of your career? For an 8% raise?

And what if its not? All they have to do is take a hostage or two, and suddenly if you don't feel well but you don't know for certain that its 100% verifiable to someone else's standards, well you better just drag your butt in and fly sick or it could be you fighting for your career and your family's livelyehod by trying to prove the unprovable.
