IMHO, the actions taken by the author, while possibly noble, did nothing to further the benefit of his wife while potentially risking his future employment opportunities. I genuinely want he and his wife to have the best outcome and I just don't see how his actions achieve this goal - in both the short term and the long.
I would have asked for unpaid time off and for Atlassian to continue to pay my medical insurance. That would be a deal which I think could have been reached.
