I've never had anyone refuse to take it, yet. Other mangers I've worked with have, but it was expected since they hadn't taken it for a few years in most cases.
Here is my disclaimer: If your whole intention is to get some kind of revenge against your manager, you will be sorely disappointed. It's pretty obvious when 1 or 2 people just go down the right side and answer everything "Strongly Disagree". Now if your manager is really that bad and it's not just a personal vendetta, that's a whole other story, and it will reflect that with everyone's answers.
Question: It's pretty obvious here that everyone feels it's ok to get personal on the SFA about mgrs, but that it's not ok for a mgr to have some kind of grudge with an hourly? I don't think either is appropriate, but from the responses on here, that is how it appears.....seems a little hypocritical.
IMO the SFA has lost all meaning that it use to have b/c of a couple reasons: Hourlies use it as a way to "get back" at their manager. Managers don't do anything with the information they do get from it, assuming is was semi-constructive. Many hourlies think that it isn't really anonymous. I can tell you for a fact that, at least at the station and district level, we have no idea what your answers were. I'm willing to bet somebody in Memphis can, but that is not the kind of information that trickles down b/c they know it would most likely result in retaliation by some.
So, I guess the answer to your question is: Unless a significant portion of your workgroup/station, say 25+%, refuse to take it.....I don't think it will matter. I would take it if I were you, and just answer honestly....if your manager is that bad, score them that way, just don't make it about one day or one issue. If you just don't answer, your manager will not know what the issues are....if they don't know what the problems are, how can they address them? Assuming they give a crap and actually want to.
My thinking is that your manager could easily say to their Sr/Director, "I don't know what the issues are b/c they won't take the SFA, so how can I be held responsible to fix a problem if I don't know what it is?" In reality, they may very well know what the problem is.....but where's the proof?
