Hi
I am so sorry for all that you and your family have been through. I can't imagine getting the old heave ho while recovering from surgery. It is true, companies have no loyalty now a days. I work in the hotel/hospitality industry and they want you to work like fools during the "season" but when it is slow, they go oops we are sorry you can't work 40 hours. I worked at a place for almost 5 years before I had to quit to take care of my DF who had lung cancer and I was there from the beginning and I was able to get my hours, that is until the boss let all of her kin folk start working there, her sister, grandmother, boyfriend, cousin by marriage.
Hope all goes well for your daughter's recovery and may she find a job that deserves her.
