We have the tag maternity-leave which is used in 29 questions currently. This is definitely a useful tag, but it really only refers to leave taken by the mother who just gave birth. There are many countries and employers that also offer parental leave to fathers and adoptive parents, and logistically it's treated pretty much the same as maternity leave. Using the maternity leave tag for these situations simply just isn't accurate (e.g this question), which is why I'm suggesting a new tag.
I would like to request that a new tag parental-leave be made and have maternity-leave assigned as a synonym that automatically redirects.
