It's hard to determine what the future holds for the employer sponsored health insurance. You did not mention bankruptcy, so it's doubtful the
company is being dissolved, however in some circumstances, a company can be bought, and then sold into parts.
It depends on the sales contract and if the company is private, it's doubtful you will have access to that info.
If you want to take out the guesswork, you can shop private health insurance rates from the green box at the top. Then once you are approved (don't do this until open enrollment, if the health plan makes it that far) unenroll.
Only attempt this for yourself or healthy members of your family.
