Quoting Uncle Obama's Banana:" So. If you work over 30 hours a week your place of work has to provide insurance and you have to pay ... [snip!] ... Sorry I'm confused. And what if you already have insurance? Do you know what the income limit will be for medicare?"
If you work over 30 hours, they have to offer you insurance and pay for part of it.
You do have to pay for your part of the insurance or you get fined.
You MAY be able to keep your insurance if it is "government approved". I cannot because mine only covers emergencies and it's not "government approved". They have not yet told us what these requirements are.
Medicare is being cut, so I believe that the requirements are being raised.
