Your medical problems are not your employers business. Period the end.

Unless it's something that prohibits you from doing your job (e.g. a paraplegic flight attendant), it's nobody's business but yours.

Think of it this way: that they hire someone else who thinks they're healthy doesn't guarantee they're hiring someone that stays healthy. In fact, they might just think they're healthy because they're less cautious and end up in a much worse spot than you.

Life happens. If the company is not equipped to deal with that, it's not your fault. It's part of running a business.

Besides, most of the problems we're talking about here are related to the shitty American healthcare system, not the business itself.
