One of the issues I am finding when rarely offered an interview is the human-resources department asking for my Social Security number to check my credit background. While I don't have any problem with my credit, I assume they also look at my age. Can this be construed as age discrimination, even if I have no way to swear in court they have taken a look at my birth date? Any suggestions as to how to confront this issue? Should I decline providing my SSN?
