I seem to remember that in past years the word "anonymous" used to show up on the yearly Employee Survey. This year, the wording says "Participation and individual responses are treated as confidential. However, comments that violate NIKE policies.... are escalated to Employee Relations". Seems that the last All Hands continues to strike a nerve. ELT can't handle to hear the truth.
Also, sign in with OKTA before you take the survey so we can be clear about who you are.
