A recent U.S. Supreme Court ruling affects cases in California and throughout the country as it helps to define what was previously a gray area regarding who is and who isn't a supervisor. This is notable as the issue of whether it's a supervisory or a non-supervisory co-worker that creates a hostile workplace will affect how a discrimination case plays out. In what is not always a completely unknowing case of employee misclassification, some employers have given supervisory responsibilities to workers without officially classifying them as such.
