In the age of the corporate intranet, one of the most obvious methods for taking the temperature of the staff is the online comment forum or discussion board. It is precisely because the solution seems so obvious that the decision to adopt it is usually made without a thoughtful consideration of the consequences. The manager who asks for employee feedback may get more than she bargained for. Save yourself some aggravation (and unpleasant surprises) by being honest about how much feedback you're really willing to accept.
