Mamajude,
For your own heart, I hope you can forgive your husband's employer. Maybe he is simply stressed by his concern for your husband and for the company as a whole.
You need all of your energy for fighting your husband's disease. He is so very blessed to have you for a partner. It sounds as if you have taken on his illness with a vengance and you're not going to let go until it is beaten. With prayer and patience, I am sure you will win. Your patience and love is a blessing to us all.
