I don't agree with these types of surveys. If it is truly anonymous and voluntary that is fine. Otherwise, employers should stay out of employees' personal business. I think a lot of companies are taking diversity the wrong way. If the hiring process is truly non-discriminatory then you will naturally have a diverse group of people at work without much effort required. Beyond that this is just data mining. Political affiliation, religion, marital status, race, sex, sexual orientation, favorite food, music preference, etc. etc. is none of an employer's concern unless it directly relates to the job. Instead of a "don't ask don't tell" policy it should be a "don't ask" policy. In other words, if an employee chooses out of their own free will to share personal information with others in the company that is their choice. I don't believe that people should go around asking them though. There is way too much of an invasion of people's privacy in today's modern society. Probing people for information is generally done with a real or perceived purpose of good intentions but on the other hand I believe adults should be treated as adults and if they aren't asking for help they shouldn't be having to divulge information so that others can "help" them when they don't need it. Enough said.
