There is no law specifying how long this leave can be: it is open-ended. As some point--though typically after weeks, NOT merely days, especially if there is still no end-date in sight--the leave effectively becomes termination, since termination does not have to be in so many words: simply not scheduling someone or letting them work can be termination, too. At that point, the worker would be able to quit because they were "constructively terminated" (effectively fired) and get unemployment, but that point--when the leave has gone on long enough--is not defined, it is subjective. As such, it is risky quiting and claiming you were fired, since you its possible the unemployment agency and/or a judge (if you appeal) will disagree with you and feel that the leave had not gone on so long that you were effectively terminated. At the least, you do want to wait weeks before trying to claim constructive termination.If your daughter wants to move on, she should be using her time on leave to update her resume, reach out to possible employers, etc. She does not need to wait for her current employer to make a decision before she acts.
