My employer promised to provide me with health insurance through the firm's small group plan (in California). A regular amount is taken from every paycheck to cover my share of the premium. I was recently diagnosed with brain cancer and began treatment. I confirmed with my employer that I could take a leave from work and that he would continue to provide my health insurance. I just found out that the boss's wife (the supposed office manager) neglected to pay the premiums for over two months and the entire group plan was cancelled - threatening my treatment. What, if anything, can I do about getting my treatment paid for?
