Hubby may be out of work for awhile but expects me to stay home and do all for his children. is this fair?help?

Your husband's children are your husband's responsibility. Your children, home, bills, etc. are your responsibility. If you need to take a job to pay bills and put food on the table then that is what you should do! If because of his illness, he can only see his kids on the weekend then too frigging bad! Life isn't fair is it? Unfortunately, the world doesn't stop because of an illness. He needs to grow up.
