    A line beginning with "Also asked:" holds alternative phrasings. Sibling
    answers share most of their heading ("Can I be fired without a reason?" and
    "...without notice?"), so the shared words outweigh the one that tells them
    apart. Aliases give the distinguishing phrasing something to match on. They
    are indexed, never displayed.
