This, yes, for my partner dying of cancer. My company offered paid leave for any reason related to my partner's treatment and illness, from days off to shuttle them to chemo to weeks when they came off it and was officially terminal. And then five weeks' bereavement. And I live in the US; this is just what my company offered. Beyond that, my manager also continuously offered or arranged for things that made our life easier, in part because it kept me productive but in larger part because she cared about us as a person, something that continued not only after their death, but after I left the company, and after SHE left that company. Hell, my manager was the only person who sent us flowers during my partner's brief last stay in the hospital before dying. (Everyone else either was able to be there in person or didn't have time to make arrangements.) My manager pulled strings with hospital staff that I didn't know she had to have flowers in my partner's room within hours. When we were making last-days preparations, we even floated making her our emergency estate executor if I was somehow incapacitated, until someone physically closer to us volunteered. So, yeah. Put him on paid leave as a brand-new, expensive employee. Even if there's no guarantee he'll stay. Even if he'll leave the company anyway. Since I'm not sure whether empathy is a factor for you, at least because everyone else on the team is watching how a manager responds to this.
