I have a friend that was a manager at at Bath and Body Works. At 43, she had a stroke. B&BW held her job while she was ill. They held her job while she rehabbed. But her stroke left her with balance and strength issues, so consequently she couldn't climb a ladder or carry boxes. both were requirements of her job, so they couldn't keep her on. She had to leave.They would have kept her if she could fulfill the job. She didn't feel as though she could, so she left.
So, sounds to me like GAP kept her job for her, but since she couldn't do what was required she was asked to leave, but she didn't. She chose to stay and do the things her doctor told her not to.
My friend could have stayed, but she was afraid she'd fall off a ladder, so she opted out.
I think this is the lady's own fault. JMHO.
