This is going to be a complicated issue that can't really be answered fully here. It's going to depend a lot on what exactly your employer did, when they did it, how they did it, why they did it, and the specific terms of the health plan and of your employment contract. To a certain extent, your employer has a right to discontinue employee benefit plans with very little notice, but they are supposed to give at least some advance notice. You should find an experienced employee benefits attorney in your area to talk to - if the employer terminated all of its health plans, with or without notice, you should at least have been offered the opportunity to purchase individual coverage with the same insurer (if it was an insured plan).
