Good points, thanks. It's my understanding that in NY, if you voluntarily leave, you aren't eligible for unemployment benefits. Our work requires a resignation letter in writing, so they'd have written proof she's resigning voluntarily. Even if she is eligible for benefits, our employer has a history of disputing unemployment claims on cases they don't believe the former employee is actually entitled to it.
I do see the company's position, but did the woman at your place know about when she'd be able to return? Or was it touch and go, depending on how she was progressing? In Jan's case, she'd have a firm return to work date after the additional 6 weeks or so are up, assuming labor goes as planned. It's still a good possibility she'd be able to return to her position, but they won't guarantee it.
