To a Younger Coworker: “You sound just like my son/daughter.”
This comment might seem harmless, but think about what you’re saying. Your coworker is not your son or daughter, and comparing a full grown Gen-Y or Millennial coworker to your child at home can be insulting.
Comparing your younger coworker to your child blurs the lines of professionalism because it immediately tells her that you view her as a subordinate. Show your younger coworker that you take her seriously and skip the comparisons to your child.
