I'm surprised that you can even compel someone to produce this information in an interview setting, considering some other things that are not legal to ask ("how much do you weigh, how tall are you . . .").
They are explicitely denying applicants the chance to present their work history. They only look at a largely irrelevant single bit of information: you don't have a job now.
This wouldn't be fair to the employer or the employee. How would you really be able to get a grasp of a potential employee's experience/fit for a position if you can't look at their previous jobs (and years of experience)?
