It would be lovely if they would... that said, I think the closest we will come anytime soon is work that gives personal or float days. It can be hard enough to get bereavement leave for human beings (my husband's work is first-degree relative leave only- so no bereavement day for your aunt or uncle, best friend, niece or nephew, etc. if they pass. Just parents, grandparents, spouses, children.) They do give three 'personal days' a year that can be used for those kinds of issues.
