My mother died about a year ago, and my father recently moved in with my family. I took vacation time to help him put their home on the market and move in with us; now that he has settled in, he has been a huge help to us. He spends time with the kids after school, makes dinner once or twice a week, and helps out with errands that are hard to get done when you work full time, like taking the car in for service. We love having him here, and he is enjoying being part of a noisy family household again.
The only thing that isn't working out is my job. When I took time off to help my dad move, my boss told me I shouldn't bring him to live with my family. She said, "he may seem fine now, but in a few years you'll be spending all of your time taking care of him." I didn't think much of it at the time, but she recently told me not to bother applying for a promotion I've had my eye on for months. The position would require more travel, among other things, and she said she didn't think it was fair to expect me to fly off at a moment's notice, given my "responsibilities at home." Is this legal?
