Rita has been diagnosed with a serious illness. She submits paperwork to her employer for medical leave and is approved. Ritas treatment will likely take longer than the leave of absence. At the end of her leave, Rita is still undergoing treatment and doesnt know when she can come back. Her employer feels bad, but wants to fill her position due to business necessity. If Rita is let go, she will lose her health benefits, which she needs to continue treatment. If she isnt let go, the employer will suffer financial harm because an employee is needed to do Ritas job. Under Federal law, what is Rita entitled to for a leave of absence and return to work? What should the employer do? Is it ethical to let Rita go?
